Finneas O’Connell and Claudia Sulewski are married. According to Vogue, the couple wed Saturday, Aug. 29, at San Ysidro Ranch in Montecito, California, and the officiant was the groom’s sister, Billie Eilish.
Inside the wedding
- The officiant: Billie Eilish led the ceremony for her brother and longtime collaborator, making it a true family affair.
- The fashion: Sulewski, an actress, creator and founder of CYKLAR Skincare, wore several Oscar de la Renta looks over the weekend, from the rehearsal dinner to the reception.
- The guests: Friends included Kristen Bell and Dax Shepard, Nina Dobrev, Emma Chamberlain, Rachel Sennott, Jason Sudeikis, and Justin and Hailey Bieber.
Their love story
The pair met on a dating app in 2018, and Sulewski soon became part of Finneas’ music. He has said she inspired some of his songs, and in 2022 she directed and appeared in the video for his “Mona Lisa, Mona Lisa.” After about seven years together, he proposed at sunset in September 2025. He later joked on The Tonight Show that keeping the proposal secret was so stressful he was just relieved when it was over.
Our take
Celebrity weddings are often huge productions, so a wedding where the officiant is your sister and closest collaborator stands out. The Eilish-O’Connell family has always kept things close-knit, and this was a fitting way to start the next chapter.
