Finneas O’Connell and Claudia Sulewski have married after seven years together, with the intimate ceremony taking place in Montecito, California, on Aug. 29.
The Grammy-winning producer and musician married Sulewski, a YouTuber, actress and founder of CYKLAR Skincare. The couple celebrated with family, friends and their dogs, Peaches and Moose.
Billie Eilish, Finneas’ sister and longtime musical collaborator, officiated the ceremony. Their parents, Maggie Baird and Patrick O’Connell, were also present.
The guest list included Justin and Hailey Bieber, Kristen Bell, Dax Shepard, Jason Sudeikis, Emma Chamberlain, Rachel Sennott, Stassie Karanikolaou and other celebrity friends. Eilish attended with her boyfriend, Nat Wolff.
Sulewski selected four Oscar de la Renta outfits for different parts of the wedding weekend, including the rehearsal dinner, ceremony, reception and after-party.
The couple first met through a dating app in 2018. A year later, Finneas told BuzzFeed that he wrote his song “Claudia” within hours of meeting her and sent part of it to Sulewski that same night.
Their creative partnership continued with Finneas’ 2022 song “Mona Lisa, Mona Lisa.” Sulewski starred in and directed its music video.
Finneas proposed in September 2025 after seven years of dating. The couple announced their engagement with a joint Instagram post captioned “Forever and ever 9.22.”
Before the wedding, Finneas told PEOPLE that he wanted Sulewski to take the lead in planning because he wanted her to love every aspect of the ceremony.
