Finneas O’Connell and Claudia Sulewski have tied the knot.
The Grammy-winning producer, 29, and the actress-YouTuber, 30, exchanged vows Saturday at San Ysidro Ranch in Montecito, California, in a ceremony that drew a packed guest list of music and Hollywood names. Billie Eilish, Finneas’s sister and frequent collaborator, officiated the outdoor proceedings, according to photos that surfaced from the event.
Justin Bieber and Hailey Bieber, Dax Shepard and Kristen Bell, Nina Dobrev, Emma Chamberlain, Jason Sudeikis, Carter Gregory, Stassie Karanikolaou and Rachel Sennott were among those spotted in attendance. Nat Wolff, Eilish’s boyfriend, also joined the celebration.
Sulewski wore multiple Oscar de la Renta designs across the wedding weekend, but saved her most dramatic choice for the main event: an off-the-shoulder ball gown with a drop-waist bodice and a scarf neckpiece. She spoke about the look in a final fitting with Vogue ahead of the big day.
“We were putting it on, and I was saying, there’s something about this dress that just demands a moment of silence,” she told the magazine.
Eilish dialed into that fitting via FaceTime and offered her own enthusiastic verdict on the gown.
“My God, I can’t believe it,” the “Birds of a Feather” singer said during the call. “You look like an angel. Sorry to be interrupting. Love you so much.”
The couple’s romance began in 2018 when they matched on a dating app. Their connection moved fast: Finneas wrote the song “Claudia” within hours of their first in-person meeting and sent it straight to her, he revealed in a 2019 the outlet Celeb interview. Sulewski later inspired his 2022 track “Mona Lisa, Mona Lisa” and appeared in its music video.
O’Connell proposed in September 2025 during a mountaintop date. The pair announced the engagement with a joint Instagram post captioned “forever and ever 9.22.”
