How Ethan Slater Went From SpongeBob to Becoming Hollywood’s Hottest Rising Star

If you had told anyone ten years ago that one of Hollywood’s most talked-about names in 2024 and 2025 would be the guy who played SpongeBob SquarePants on Broadway, they probably would have laughed. But then again, nobody laughed when they actually saw Ethan Slater do it. 

He has spent his whole career making people reconsider their expectations of him, of the roles he takes, of what a Broadway musical can actually do. And now, with two blockbuster Wicked films under his belt, a Tony Award nomination on his resume, a new relationship with one of the biggest pop stars alive, and an off-Broadway play he wrote himself on the way, there has never been a better time to get the full picture.

Quick Facts About Ethan Slater

Where He Came From: Growing Up in Silver Spring, Maryland

The story begins in Washington, D.C., where Ethan Samuel Slater was born on June 2, 1992, to a Conservative Jewish family. His father, Jay Slater, worked at the U.S. Food and Drug Administration. His mother was Ellen Goldmuntz. He is the third of their children, with two older sisters named Sara and Tamara.

The early years were shaped by faith, community, and then, sharply, by grief. His mother passed away when he was just seven years old. The loss was profound, and by multiple accounts it left a mark that is still visible in the kind of roles he is drawn to and the emotional depth he brings to them. His father eventually remarried, adding a stepmother and two younger half-brothers to the family.

They lived in Silver Spring, Maryland, a suburb of D.C. with a sizable Jewish community and a strong local arts scene. He attended Ohr Kodesh Congregation and went to Charles E. Smith Jewish Day School. Every summer until he was 16, he went to Ramah, a Jewish summer camp where his father worked. The camp placed a heavy emphasis on art and music, probably did more to shape him as a performer than any single class or audition.

What is interesting about his backstory is that he was not a kid who only did theater. He wrestled. He was good enough to join the wrestling team in college, which tells you something about the physical discipline and competitive instinct underneath the musical theater exterior that would eventually define his most famous stage work.

School, Wrestling, and the Road to Vassar

He graduated from Georgetown Day School in Washington, D.C., a progressive, academically rigorous private school that tends to produce thoughtful, socially aware graduates. Drama was a clear interest, but his father had understandable concerns about the stability of an arts career. At various points, political science and pre-law were apparently on the table as more practical alternatives.

He went to Vassar College in Poughkeepsie, New York, where he majored in drama and threw himself into the department’s productions. He joined the wrestling team. He also began the first connections to the theatrical world that would eventually launch his professional career during his time at Vassar, he auditioned for a Shakespeare apprenticeship workshop, which led directly to an audition for a director named Tina Landau who was working on a project nobody had a name for yet.

That audition, in 2012, while he was still a student, was for what would eventually become SpongeBob SquarePants: The Broadway Musical. He graduated in 2014 with a Bachelor of Arts in Drama. He moved to New York. He started working.

How Tall Is Ethan Slater and Other Physical Details

He stands at approximately 5 ft 10 in (178 cm), which means he played SpongeBob, a character who is supposed to be a small, rectangular sea sponge, while being of perfectly average human height. The production’s costume and staging design handled this with impressive theatrical ingenuity.

His ethnicity is white and Jewish. He was raised in Conservative Judaism, attending synagogue at Ohr Kodesh in Silver Spring. His faith appears to remain a meaningful part of his identity, the values of community, storytelling, and moral seriousness that characterize Conservative Jewish practice are all visible in the kinds of projects he gravitates toward.

He is a trained wrestler, having competed at the collegiate level at Vassar, a fact that makes his physical performance style in SpongeBob considerably less surprising when you know it.

How a Maryland Kid Became Broadway’s Most Unlikely Star

This is the part of the Ethan Slater bio that most people want to know about, and it deserves proper attention.

SpongeBob SquarePants: The Broadway Musical is not a show that most people would have predicted would work. The idea of adapting a beloved, absurdist, deeply weird Nickelodeon cartoon about a sponge who lives in a pineapple under the sea into a serious Broadway production with original songs by indie artists like They Might Be Giants, Sara Bareilles, John Legend, and David Bowie sounded, on paper, like a gimmick.

The show, directed by Tina Landau (the same director he had first auditioned for in 2012), premiered in Chicago in 2016 and moved to Broadway in 2017, opening at the Palace Theatre in New York. The production was visually dazzling, emotionally surprising, and rested entirely on the performance of its lead actor. SpongeBob is on stage for virtually every minute of the show. He has to sing, dance, do physical comedy, carry dramatic scenes, and somehow channel the wide-eyed optimism of a cartoon character without ever becoming a cartoon himself.

The performance Slater gave was, by the consensus of critics who saw it, extraordinary. He brought genuine warmth, enormous physical commitment, and an ability to play SpongeBob’s fundamental decency and joy without condescension or irony. The show earned multiple Tony Award nominations, including one for him personally for Best Actor in a Musical, a category in which he was competing against established Broadway names. He did not win the Tony, but he won the Drama Desk Award, the Theatre World Award, the Outer Critics Circle Award, and the Broadway Beacon Award.

The show ran on Broadway until December 2018, and during its run it became a cultural moment that nobody had quite expected. The cast recording charted. The production attracted audiences who had never set foot in a Broadway theater. And the actor at its center became one of the most talked-about young performers in the American theater.

He was 25 when the show opened. He had been working toward this for more than a decade. Nobody was surprised that it worked except, the people who had dismissed the concept before the curtain went up.

Life in Hoboken and the Theater Years in Between

During the Broadway years and the work that followed, he made his home in Hoboken, New Jersey, the dense, creative, waterfront community just across the Hudson from Manhattan that has long been a home for artists who want New York access without Manhattan rents and Manhattan chaos. It was a practical choice for a working theater actor. It was also, reportedly, where he and his wife Lilly Jay built their life together during the years when things were good.

After the SpongeBob run ended, he kept working and the range of roles he took demonstrates something important about his approach. He was not interested in consolidating into a type. He played Mordred in Camelot (2019), a villain turn that is about as far from SpongeBob as you can travel within the same art form. He played The Balladeer and Lee Harvey Oswald in Assassins (2021–2022), the Sondheim musical about people who tried to kill American presidents, a dark, demanding ensemble piece that requires total character transformation from its cast. He played Max Weinbaum in Good Night, Oscar (2022).

He also wrote and composed. His EPs Wanderer (2019) and Life Is Weird (2020) demonstrated a singer-songwriter sensibility alongside the theatrical voice. He wrote short films. He composed music. The picture that emerges from these years is of someone who is constitutionally incapable of doing only one thing.

He also appeared on television, a guest role as Riley Porter in a Law & Order: SVU episode in 2018, and a brief appearance in The Marvelous Mrs. Maisel. Screen work, at this point in his career, was supplementary to the stage. 

Wicked (2024): The Role That Made Him a Household Name

In December 2022, it was announced that he had been cast as Boq in Jon M. Chu’s two-part film adaptation of the beloved Broadway musical Wicked. The rest of the cast, Cynthia Erivo as Elphaba, Ariana Grande as Glinda, Jonathan Bailey as Fiyero, Michelle Yeoh, Bowen Yang was announced alongside him. Filming began in England almost immediately.

Before we get to what happened off-camera during production, it is worth explaining who Boq actually is, because he is genuinely one of the most interesting characters in the story.

Who Is Boq in Wicked

Boq Woodsman starts the story as a Munchkin student at Shiz University, sweet, earnest, a little bit awkward, and hopelessly infatuated with Glinda. He follows her around like a lost puppy. He is, at the beginning, essentially comic relief with a tragic undertone.

But his arc does not stay simple. Through a series of events involving Elphaba’s magic and Nessarose’s desperation, Boq ends up having his heart magically shrunk, and in Elphaba’s attempt to save his life, she inadvertently transforms him into the Tin Man, the heartless figure from The Wizard of Oz. It is one of the musical’s most devastating turns, and it gives the actor playing the role a genuine dramatic journey to navigate: from lovestruck student to angry, betrayed tin-plated man without a heart.

In Wicked: For Good (2025), the second part of the story, the Tin Man transformation is complete. Boq, now the Tin Man, has turned against Elphaba, blaming her for what happened to him, driven by grief and misplaced fury into the very witch hunt he once would never have joined.

The first film grossed over $700 million worldwide against a budget of approximately $145 million, making it one of the biggest musical adaptations in cinema history. His performance as Boq was widely praised, and he was reported to have been paid approximately $350,000 for the role, a figure that will almost certainly look very different on any sequel or future project.

He was reportedly paid around the same for Wicked: For Good, which opened in November 2025 to similarly enormous box office numbers.

Ethan Slater and Lilly Jay: The Marriage, the Baby, and the End

This is the part of his story that made him a tabloid headline, and it is worth telling properly rather than in shorthand.

He and Lilly Jay had known each other since they were teenagers. They started dating in 2012, apparently while Slater was still in college at Vassar, though some sources place the beginning of their relationship as early as high school. She studied to become a clinical psychologist. He built his theater career. They moved through their twenties together.

They married in November 2018, the same year he was nominated for a Tony Award. She was at Radio City Music Hall that night watching him walk the red carpet. The photographs from that evening show two people who looked genuinely happy.

In August 2022, they welcomed a son. Two months later, they packed up their lives and moved to London, where filming for Wicked was based. Lilly Jay went with him, newborn in tow, to support his career. She has written about this decision herself with remarkable candor and without apparent bitterness toward the reader, though clearly with enormous grief at how it ended.

She wrote in an essay for The Cut: “I confidently moved to another country with my 2-month-old baby and my husband to support his career.” She describes not understanding the growing distance between them during that period. She describes watching the world celebrate the film while processing what she called “the public downfall of my marriage.”

In July 2023, he filed for divorce in New York. The finalization came in September 2023. The terms were sealed. They share custody of their son, whose name has been kept out of the public eye by both parents, which is one of the few things both sides have agreed on without apparent conflict.

Ariana Grande and Ethan Slater: The Full Story

The relationship between Pop superstar Ariana Grande and Tony-nominated Broadway actor Ethan Slater stood as one of Hollywood’s most heavily scrutinized romances of recent years. What began as a high-profile set romance during the filming of Wicked eventually quietly ran its course after nearly three years together.

The Spark on the Wicked Set (Late 2022)

Before late 2022, Ethan Slater was best known to theater audiences for originating the title role in Broadway’s SpongeBob SquarePants: The Broadway Musical. That shifted when he was cast as Boq in Jon M. Chu’s feature film adaptation of Wicked, starring alongside Ariana Grande as Glinda.

Filming began in England in late 2022. At the time, both actors were married to other people:

• Ariana Grande: Married to real estate broker Dalton Gomez since May 2021.
• Ethan Slater: Married to his high school sweetheart Lilly Jay, with whom he shared a newborn son.

July 2023: The Unraveling and Public Scrutiny

The first visible indication of personal shifts occurred in July 2023, when Grande was photographed at the Wimbledon tennis tournament without her wedding ring. Within days, a cascade of public separation announcements followed:

• July 17, 2023: Outlets confirmed Grande and Gomez had separated.
• July 20, 2023: News broke via Entertainment Tonight that Grande and Slater were officially dating.
• 2024 Divorce from Jay finalized: Early 2026 Relationship with Grande ends, confirmed by outlets in June 2026

Sources close to the couple maintained that their romance did not begin until both parties had separated from their respective spouses. However, the tight timeline sparked substantial public skepticism. Lilly Jay publicly noted that her family was collateral damage in the aftermath, while Grande pushed back against external judgment in a September 2024 Vanity Fair interview, noting how tabloids sensationalized life changes experienced during a two-year overseas shoot.

Public Romance & Eternal Sunshine (2023–2025)

Despite the noise, the pair settled into a disciplined, low-key relationship, balancing public support with personal privacy:

1. Album Inspirations: In March 2024, Grande released her album Eternal Sunshine, which featured tracks widely interpreted as reflecting her romance with Slater, including lines praising a “good boy” on her side.
2. Public Appearances: Grande attended Slater’s Broadway performance in the Spamalot revival in late 2023. They were later spotted together at the 2024 Stanley Cup Finals in Florida.
3. Official Milestones: By late 2024, both actors had finalized their respective divorces. They made their relationship Instagram-official in November 2024 and appeared alongside each other throughout the massive global press tour for Wicked.
4. Career Support: In March 2025, Grande publicly celebrated Slater’s off-Broadway play Marcel on the Train, which he co-wrote and starred in, sharing congratulatory messages on her social channels.

June 2026: The Quiet Split

In June 2026, reports confirmed that Ariana Grande and Ethan Slater had officially ended their romantic relationship after nearly three years together.

Insiders confirmed to outlets such as People and TMZ that there was no drama behind the separation; the relationship simply ran its natural course as both adjusted to demanding career schedules following the conclusion of the Wicked promotional eras.

What Ethan Slater Is Doing Now in 2026

As of 2026, the career trajectory is pointing sharply upward.

He is set to star in Marcel on the Train, an off-Broadway production about legendary French mime Marcel Marceau and in a characteristic move, he did not just agree to play the role. He co-wrote the play. The project continues his pattern of gravitating toward singular, physically demanding characters whose emotional interiority is expressed through their bodies as much as their voices.

He is raising his son, whose life both parents are clearly intent on protecting from the intensity of public attention that surrounds both of them. He has signed on for further screen projects that have not been fully announced.

The SpongeBob era put him on Broadway’s map. The Wicked era put him on the world’s map. What comes next is, by any reasonable measure, entirely up to him.

Complete Theatre Career

His stage credits, beyond SpongeBob and the Wicked films, demonstrate the range that defines him as a performer.

Movies and TV Shows

His screen credits, while fewer than his stage work, are growing:

As a writer and composer, he has credits on the short films New Mayor of New York (2015) and Intervenors (2022), in which he also appeared as Miles.

His EPs as a recording artist, Wanderer (2019) and Life Is Weird (2020), are available on streaming platforms and worth a listen for anyone curious about what he sounds like outside the context of a stage production.

Ethan Slater’s Net Worth

The honest answer is that his net worth is still in the early stages of the trajectory you would expect given where his career is going. Current estimates place it somewhere between $1 million and $3 million, with most sources settling around $2 million.

Broadway careers, even celebrated ones, do not generate film-level income. The SpongeBob years were artistically triumphant and financially decent, but decent is not the same as wealthy. His reported payment for each of the Wicked films was around $350,000, significant, but not yet at the level of a lead actor in a franchise.

What changes the calculation going forward is the combination of his profile post-Wicked, the fact that his partner is one of the most commercially powerful entertainers in the world (which raises visibility if nothing else), and his demonstrated willingness to take on projects as a writer and creator rather than just a performer. Actors who create their own work have more than one income stream, and more than one form of leverage.

Awards and Recognition

• Tony Award nomination: Best Actor in a Musical, SpongeBob SquarePants: The Broadway Musical (2018)
• Drama Desk Award: Outstanding Actor in a Musical, SpongeBob SquarePants (2018)
• Outer Critics Circle Award: Outstanding Actor in a Musical (2018)
• Theatre World Award (2018)
• Broadway Beacon Award (2018)

Multiple critics’ awards from regional and national theater organizations for the SpongeBob production, and positive critical reception for his work in Assassins, Spamalot, and the Wicked films.

Ten Things About Ethan Slater That Most People Don’t Know

1. He Was Working on Spongebob While Still in College

He auditioned for Tina Landau’s unnamed project in 2012, two years before he graduated from Vassar. The show did not open on Broadway until 2017, five years of development that he was part of from near the beginning.

2. He Was a Competitive Wrestler

He competed on Vassar’s team during college, which explains the physical fearlessness and stamina he brought to the SpongeBob role.

3. His Character in Wicked Becomes the Tin Man

Boq’s transformation is one of the most emotionally loaded moments in the story and the actor playing him has to carry the audience from lovesick student to betrayed and heartless figure across two films.

4. He Moved to London with a Two-Month-Old Baby to Film Wicked

His wife Lilly Jay made the move with him to support the role. The marriage did not survive the experience.

5. He Was Reportedly the Understudy for a Role He Hadn’t Even Auditioned for Originally

During his early training years, his work on Shakespeare apprenticeships and Tina Landau’s development process put him in rooms that led, indirectly, to SpongeBob in ways that were not straightforward or predicted.

6. He Co-Wrote the Play He Is Starring in Next

Marcel on the Train, about mime Marcel Marceau, is not just an acting job. He wrote it. This is becoming a pattern.

7. He Grew up Watching Spongebob Squarepants as a Child in Silver Spring, Maryland

This makes his casting as the character on Broadway one of those stranger-than-fiction symmetries that the entertainment industry occasionally produces.

8. Christopher Fitzgerald Originated the Role of Boq on Broadway

On the day Slater was asked to audition for the film, he was in the room doing a table read for a different musical and happened to be playing Fitzgerald’s identical twin character. He submitted his audition tape that same day.

9. He Has Released Two Solo EPS

As a singer and songwriter, independent of his theatrical work, Wanderer (2019) and Life Is Weird (2020).

10. Ariana Grande Attended His Spamalot Performance on Halloween in a Paper Crown

This is simply one of the better celebrity couple moments in recent memory and deserves to be on the record.
