Congratulations to Finneas O’Connell on his marriage to Claudia Sulewski — and congratulations to his sister, Billie Eilish, who can now add “wedding officiant” to her résumé. A joyful day all around!
O’Connell, who performs under his first name only, Finneas, officially married his partner of eight years, Sulewski, on Saturday in Montecito, CaltFinneasifornia. And, according to the photos posted by Deuxmoi, it looks as though the ceremony was officiated by Eilish (no word yet on whether she sang during the celebration, however). The photos also show that Nina Dobrev, Kristen Bell, Emma Chamberlain, Rachel Sennott, and the Biebers were in attendance too. According to Vogue, the bride wore four looks by Oscar de la Renta: one for the rehearsal dinner, one for the ceremony, one for the reception, and a final dress for the after-party. Of course, Sulewski was most excited for the ceremony dress, which was a strapless, drop-waist ball gown accessorized with a long, dramatic scarf.
O’Connell and Sulewski first met on the apps in 2018, and O’Connell famously wrote the song “Claudia” just hours after their first date. By 2019, they had bought their first house together but didn’t get engaged until September 2025. “forever and ever 9.22,” they wrote in their shared Instagram announcement. While additional details about the wedding remain under wraps, we assume the music was top tier.
