Finneas O’Connell and longtime partner Claudia Sulewski were married in Montecito, California, in a ceremony officiated by O’Connell’s sister, pop star Billie Eilish, according to reports and published images.
Close circle and high-fashion moments
Vogue published an exclusive look at Sulewski’s final wedding-dress fitting and reported that the couple — together for eight years — exchanged vows on Saturday surrounded by family and friends. Photographs shared by celebrity account DeuxMoi and reporting by TMZ showed Eilish standing between the bride and groom to officiate.
“My God, I can’t believe it,” Eilish exclaimed during a fitting, according to Vogue. “You look like an angel. Sorry to be interrupting. Love you so much!”
The wedding included a notable fashion element: Vogue reported that Sulewski wore four separate Oscar de la Renta looks across rehearsal, ceremony, reception and after-party events. During the final fitting captured by Vogue, Eilish viewed Sulewski’s ivory ceremony dress, which was accessorized with a pleated scarf.
Guests and cultural connections
Published images and reports identified several well-known attendees. Those present included actors and influencers such as Nat Wolff, Nina Dobrev, Kristen Bell, Emma Chamberlain and comedian Rachel Sennott, alongside celebrity couple Justin and Hailey Bieber. Representatives for O’Connell did not immediately comment to Entertainment Weekly.
The ceremony’s public details add to the cultural interest in the O’Connell–Eilish family dynamic: Finneas is a Grammy-winning producer and frequent collaborator with his sister Billie Eilish, whose role as officiant underscores their close personal and professional relationship.
Background and songwriting link
Finneas and Sulewski first connected after meeting on a dating app in 2018. The couple’s relationship has been documented in interviews and social media over the years. O’Connell has written multiple songs inspired by Sulewski; Vogue and other reporting note that he began the song “Claudia” on the day they met and released it in 2019.
The wedding brings together threads from music, fashion and influencer culture. Sulewski is known as a YouTuber, actress and founder of the skincare line Cyklar, a profile that complements O’Connell’s presence in mainstream music and high-fashion reporting.

For fans and followers of the siblings’ work, the wedding is a reminder of how closely personal and creative lives can intersect in pop culture: O’Connell’s career as a songwriter and producer has long been intertwined with Billie Eilish’s rise, and his publicly shared songs about Sulewski connect his private life to his catalogue.
As with many high-profile weddings, initial public details have come through fashion reporting and social-media photos rather than official statements from representatives. Vogue’s coverage emphasised Sulewski’s fittings and designers, while celebrity photo accounts and TMZ published photographs of the ceremony, including Eilish’s role as officiant. Entertainment Weekly sought comment from O’Connell’s representatives but had not received a response at the time of reporting.
Beyond the immediate spectacle, the event will likely be of ongoing interest to music and style media given the prominence of those involved and the overlaps between social-media influence, celebrity fashion and contemporary pop music.
