Finneas O’Connell, the Grammy-winning musician and Billie Eilish’s brother, is officially engaged to longtime girlfriend Claudia Sulewski. The couple shared the happy news on Instagram Wednesday, Sept. 24, revealing that O’Connell proposed during a romantic sunset outing on Sept. 22.
Who Is Finneas’ Fiancée Claudia Sulewski?
The 28-year-old singer-producer, who performs under the name FINNEAS, and Sulewski, 29, have been together for seven years after meeting on a dating app in 2018, per Just Jared. Alongside their announcement, the pair posted photos from the helicopter ride leading up to the proposal, a video from the scenic setting, and snapshots of Sulewski’s cushion-cut diamond engagement ring. Their caption read: “forever and ever 9.22.”
Sulewski is a YouTuber and actress, and has long been an important part of O’Connell’s personal and creative life. In 2019, he revealed to BuzzFeed that he wrote the song “Claudia” just hours after meeting her, sharing parts of it with her the same night.
Claudia Sulewski’s Career & Relationship With Finneas
According to People, Sulewski launched her YouTube channel at age 13 and built an audience with beauty tutorials and lifestyle content. By 2014, she moved from Illinois to Los Angeles to pursue entertainment full time. She soon became a Teen Vogue host, covering red carpets and major industry events. Today, she has millions of followers across Instagram, YouTube, and TikTok.
Her acting career includes the Hulu series “The Commute,” the dramedy “I Love My Dad” starring Patton Oswalt, and other film and TV roles.
The couple’s milestones go beyond their respective careers. In 2019, they bought a house together in Los Angeles, which features a recording studio for O’Connell and an office for Sulewski. That same year, they adopted a pit bull named Peaches, who often appears in their social media posts.
O’Connell has consistently shared heartfelt tributes to Sulewski. On their fourth anniversary in 2022, he wrote on Instagram: “You’d have to scour the globe to try to find someone equally as talented, creative and hard working as you are, my love. Then you’d have to do it a second time to try to find someone as kind, thoughtful and generous. A third time to find someone as funny, a fourth to find someone as loving, a fifth to find someone as beautiful. How you manage to be every one of these things all at once, will forever be the impossibility of you. Happy anniversary, Baby, I love the hell out of you.”
Claudia Sulewski’s Relationship With Billie Eilish
Sulewski also shares a close bond with O’Connell’s sister, Billie Eilish, and the two frequently appear together in social media posts and support one another at major events. Sulewski joined Eilish and O’Connell at the Los Angeles premiere of “Barbie” in 2023, celebrating the sibling duo’s Grammy-winning soundtrack hit “What Was I Made For?”
From YouTube star to actress and now fiancée, Sulewski has been by O’Connell’s side through career highs, family milestones, and red carpet appearances. With their engagement, the longtime couple is preparing for their next chapter — one that began with a dating app connection in 2018 and has since grown into a creative and deeply personal partnership.
