Finneas O’Connell and Claudia Sulewski have officially tied the knot!
O’Connell, a musician, producer and Billie Eilish‘s brother, and Sulewski, a YouTuber, actress and founder of Cyklar skincare, got married on Saturday in Montecito, California, surrounded by family and friends
The Grammy and Oscar winner knew something was special about Sulewski from the moment they first met on a dating app in 2018. He previously told BuzzFeed that he wrote his song “Claudia” on the first night they spent together. The singer also wrote his 2022 song “Mona Lisa, Mona Lisa” about Sulewski
After years together, they got engaged in September 2025 when O’Connell popped the big question during a romantic sunset proposal. “Forever and ever 9.22,” the pair captioned a joint Instagram post at the time
Last year, during an appearance on The Tonight Show Starring Jimmy Fallon, O’Connell opened up about the proposal and the challenge of keeping it a secret from Sulewski
“I’m very relieved that it happened,” he said. “I feel like it really taught me that I’m not cut out to rob banks or steal cars or something because I was keeping a joyous, happy secret for several weeks, and it ate me alive.”
Neither O’Connell nor Sulewski has personally shared details about their big day yet, but Vogue reportedSulewski wore four looks throughout her wedding weekend, all designed by Oscar de la Renta, including one for the rehearsal dinner, another for the ceremony, a third look for the reception and the last one for the afterparty
