Finneas and Claudia Sulewski Wed in Santa Barbara With Sister Billie Eilish as Officiant
Finneas, 29, and Claudia Sulewski, 30, exchanged vows at San Ysidro Ranch in Santa Barbara on August 30. Billie Eilish officiated the intimate ceremony, with parents Maggie Baird and Patrick O'Connell present. The couple, engaged since September 2025, celebrated with guests including Justin and Hailey Bieber, and Sulewski wore four Oscar de la Renta outfits across the wedding weekend.
The wedding weekend featured four distinct Oscar de la Renta ensembles for Sulewski, spanning rehearsal dinner, ceremony, reception, and after-party. Finneas and Sulewski first connected on a dating app in 2018, and he wrote the song “Claudia” within hours of their first meeting, sending her the initial verse that night. Their creative partnership later extended to his 2022 solo track “Mona Lisa, Mona Lisa,” which she directed and starred in.
The couple’s engagement was announced in September 2025 after seven years together, marked by a sunset hillside proposal. Their dogs, Peaches and Moose, were present at the ceremony, which also drew a guest list mixing music, comedy, and fashion figures, including the Biebers, Sennott, Chamberlain, and Bell.
This high-profile celebrity wedding could reinforce the cultural visibility of long-term relationships formed through dating apps, normalizing that path for public figures. The presence of Billie Eilish as officiant may also deepen fan interest in the family’s creative bond, potentially boosting engagement with their music. For fans, such events often serve as aspirational lifestyle content, but they may also prompt reflection on privacy boundaries for celebrities sharing intimate milestones.
