Musician Finneas O’Connell and his longtime girlfriend, actress Claudia Sulewski, were married Saturday at San Ysidro Ranch in Santa Barbara, California. The ceremony was officiated by O’Connell’s sister, Grammy-winning artist Billie Eilish.
Attendees included Justin Bieber and Hailey Bieber, Dax Shepard, Kristen Bell, Nina Dobrev, Emma Chamberlain, Jason Sudeikis, and Rachel Sennott. Eilish's boyfriend, Nat Wolff, was also present.
Sulewski wore multiple Oscar de la Renta designs throughout the wedding weekend, with her ceremony gown being an off-the-shoulder ball gown with a drop-waist bodice and a scarf neckpiece.
O’Connell, 29, and Sulewski, 30, first met in 2018 through a dating app. O’Connell has stated that he wrote the song "Claudia" hours after their first in-person meeting. Sulewski was also the inspiration for his 2022 track "Mona Lisa, Mona Lisa" and appeared in its music video.
The couple announced their engagement in September 2025 via an Instagram post captioned "forever and ever 9.22."
