Finneas O’Connell, professionally known as FINNEAS, is an American singer, songwriter, record producer, composer, musician and actor who has become one of the most influential behind the scenes figures in contemporary pop music. Born on July 30, 1997, in Los Angeles, California, he is widely recognised for his work as a producer and co songwriter with his younger sister, Billie Eilish, while also maintaining a successful solo career. His work has earned major industry recognition, including multiple Grammy Awards and Academy Awards.
Finneas first became widely known for helping shape Billie Eilish’s distinctive sound, particularly through the production and songwriting behind songs including “Ocean Eyes,” “Bad Guy” and “What Was I Made For?” His creative partnership with Eilish has produced commercially successful albums, major awards and music for film, while his own work has established him as a singer and songwriter in his own right.
Outside his work with Billie Eilish, Finneas has built an independent career encompassing solo albums, film and television composition, acting and live performance. His solo releases include Blood Harmony, Optimist and For Cryin’ Out Loud!, while his more recent work has included music for BEEF Season 2. In his personal life, he married actress and creator Claudia Sulewski in August 2026, adding another major development to his public profile.
Finneas O’Connell Early Life
Finneas Baird O’Connell was born on July 30, 1997, in Los Angeles, California, to Maggie Baird and Patrick O’Connell. He grew up in a creative household, with both parents involved in acting and music. His younger sister is Billie Eilish, who would later become his most important creative collaborator. Growing up in Los Angeles exposed him to the entertainment industry from an early age and helped shape his interest in performing and songwriting.
Finneas began writing songs and experimenting with music while he was still young. He learned several instruments and eventually developed an interest in music production, teaching himself many aspects of recording and production. His early creative work was not limited to music, as he also pursued acting and appeared in productions including Bad Teacher, Modern Family and Glee.
As a teenager, Finneas increasingly focused on songwriting and production. He initially wrote songs for himself and his band, the Slightlys, before beginning to collaborate closely with Billie Eilish. His production of “Ocean Eyes,” which Eilish released in 2016, became a major turning point and helped establish the siblings as an important songwriting and production partnership.
Finneas O’Connell Education
Finneas and Billie Eilish were homeschooled by their parents, Maggie Baird and Patrick O’Connell. Their parents designed an educational environment that allowed the siblings to pursue their creative interests while continuing their academic development. This gave Finneas substantial time to explore songwriting, acting, instruments and music production during his formative years.
His homeschooling also allowed him to develop practical creative skills at an unusually young age. Rather than following a conventional school based path, Finneas spent considerable time writing songs, learning instruments and experimenting with recording technology. He eventually taught himself music production and began building the technical skills that would become central to his professional career.
Finneas did not follow the traditional university route associated with many musicians and producers. Instead, his education continued through practical experience in acting, songwriting, recording, production and collaboration. His development as a producer was largely shaped by years of hands on experimentation, particularly through his work with Billie Eilish.
Finneas O’Connell Career
Finneas began his entertainment career as an actor before becoming internationally recognised as a songwriter and producer. He appeared in the film Bad Teacher in 2011 and later took roles in productions including Life Inside Out, Modern Family and Glee. His early acting work gave him experience in film and television before music became the dominant focus of his professional life.
His career changed significantly when he began working with Billie Eilish. Finneas wrote and produced “Ocean Eyes,” which became a breakthrough song for Eilish after its release in 2016. He subsequently became the primary producer and songwriting collaborator behind much of her catalogue, helping develop the intimate production style that became associated with her music.
Finneas and Eilish went on to achieve major international success with projects including When We All Fall Asleep, Where Do We Go? and music for major films. Their song “No Time to Die” won the Academy Award for Best Original Song, while “What Was I Made For?” from Barbie earned another Academy Award. Their work has also brought Finneas numerous Grammy Awards and established him as a highly regarded producer and songwriter.
Alongside his production career, Finneas developed his own identity as a recording artist. He released his debut EP Blood Harmony in 2019 and later released the albums Optimist and For Cryin’ Out Loud! His solo work has allowed him to explore alternative pop and more personal songwriting outside his collaborative work with Eilish.
Finneas has also expanded into composition and soundtrack work. He has written music for film and television projects and contributed to productions including The Fallout, Disclaimer and BEEF Season 2. In 2025, he also became part of the musical group The Favors with singer songwriter Ashe. His career therefore spans production, songwriting, solo music, composition, acting and live performance.
Finneas O’Connell Withdraws From Ed Sheeran’s Tour in Solidarity With Macklemore
Finneas is currently attracting public attention after withdrawing from Ed Sheeran’s Loop Tour in September 2026. He was scheduled to perform as an opening act on six South American dates in November, but announced that he would no longer participate after rapper Macklemore was removed from the tour following public comments supporting Palestinians. Finneas joined other supporting acts, including Lukas Graham and Aaron Rowe, as well as Sheeran’s touring band Beoga, in leaving the remaining tour dates.
The decision followed a dispute surrounding Macklemore’s removal from the tour. Macklemore had made pro Palestinian comments during performances, while Ed Sheeran said the decision to remove him was made by the tour promoter and venues rather than by Sheeran personally. Finneas publicly expressed support for artists speaking about oppression, saying that artists should not be silenced when speaking up for oppressed people.
Finneas’s withdrawal has placed him in a wider public discussion about artistic expression, political speech and the role of musicians in responding to international conflicts. The development is particularly notable because Finneas has maintained a major profile as a producer and performer while also becoming increasingly visible in public discussions beyond music.
Finneas O’Connell Personal Life
Finneas has been in a long term relationship with actress, creator and entrepreneur Claudia Sulewski since 2018.

Finneas and Claudia Sulewski married on August 29, 2026, in Montecito, California, following approximately eight years together. The intimate ceremony was attended by family and celebrity friends, while Billie Eilish served as the officiant. Sulewski wore multiple custom Oscar de la Renta outfits during the wedding celebrations.
Family remains an important part of Finneas’s personal and professional life. His mother is actress and musician Maggie Baird, his father is actor Patrick O’Connell and his younger sister is Billie Eilish. His close creative partnership with Billie has been one of the defining features of his career, with the siblings continuing to collaborate on music and major projects.
