Finneas O’Connell is officially off the market.
The artist, producer, and brother to Billie Eilish has tied the knot with his longtime partner Claudia Sulewski after eight years together, according to *Vogue*. The outlet, which published an exclusive look at Sulewski’s final wedding dress fitting, confirmed that she and O’Connell tied the knot in Montecito, Calif., on Saturday, surrounded by family and friends.
Their wedding was reportedly officiated by Eilish, O’Connell’s superstar sister and frequent collaborator, according to TMZ and photos of the ceremony posted by celebrity gossip account, DeuxMoi.

The pictures see Eilish standing between her brother and new sister-in-law to officiate the ceremony. The snaps also showed such attendees as Nat Wolff, Nina Dobrev, Kristen Bell, Emma Chamberlain, Rachel Sennot, and the Biebers, Justin and Hailey.
Representatives for O’Connell did not immediately respond to* *‘s request for comment.
Sulewski wore four Oscar de la Renta looks for the occasion, per *Vogue*, donning one gown for the rehearsal dinner, one for the ceremony and first dance, another for the reception and a new look for the after-party. During the final fitting, she dialed in Eilish to give her a look at her ivory ceremony dress, which was accessorized with a pleated scarf.

“My God, I can’t believe it,” Eilish exclaimed. “You look like an angel. Sorry to be interrupting. Love you so much!”
O’Connell previously shared that he immediately knew he had found something special with Sulewski — a YouTuber, actress, and founder of Cyklar skincare — after meeting on a dating app in 2018. In fact, he wrote the first verses of his song “Claudia” the day that they met.
“I sent her the first part and she texted me back, ‘You’re trouble,’” he told *Buzzfeed* in 2019.

The song begins, “I think you’re gonna change my plans, With those emerald eyes / But you don’t even understand, how much they’re on my mind / Feels like I’m breathin’ in and out without permission, Waitin’ on your badges by the phone / I might be headed in the opposite direction, But I’d love to drive you home.”
A year after meeting, the couple bought their first house together. In 2022, O’Connell penned his song “Mona Lisa, Mona Lisa” about Sulewski who starred in the intimate music video that accompanied the release.

The couple announced their engagement in September 2025 after seven years together, sharing a joint Instagram post captioned “forever and ever 9.22.” Among the carousel of photos was a shot of the duo hugging on a hillside at sunset and another of O’Connell down on one knee.
O’Connell later told Jimmy Fallon that pulling off the proposal was no easy feat.
“I’m very relieved that it happened,” he said during an October 2025 interview. “I feel like it really taught me that I’m not cut out to rob banks or steal cars or something because I was keeping a joyous, happy secret for several weeks, and it ate me alive.”
