Finneas Marries Claudia Sulewski in San Ysidro Ranch Wedding Officiated by Billie Eilish
Finneas O’Connell and longtime girlfriend Claudia Sulewski are officially married, tying the knot in a star-studded outdoor ceremony at the San Ysidro Ranch in Santa Barbara, California, on Saturday, Aug. 30.
The wedding brought together close family, including parents Maggie Baird and Patrick O’Connell, alongside an extensive guest list of A-listers, creators, and close friends. The couple’s rescue dogs, Peaches and Moose, also took part in the celebrations as flower dogs, bringing a deeply personal touch to the estate.

Set against the picturesque backdrop of the Santa Barbara foothills, the celebration drew a prominent crowd from the worlds of music, film, and digital media. Among the notable attendees spotted at the venue were Justin and Hailey Bieber, Jason Sudeikis, Kristen Bell, Dax Shepard, Emma Chamberlain, Rachel Sennott, Nina Dobrev, Rebecca Black, Devon Lee Carlson, Stassie Karanikolaou, and Jesse Jo Stark. Billie Eilish was accompanied by her boyfriend, Nat Wolff, who also joined the family for the weekend’s festivities.

The matrimonial milestone follows a seven-year relationship that began on a dating app in 2018. The couple officially announced their engagement in September 2025 via a joint Instagram post captioned “forever and ever 9.22,” featuring snapshots from a romantic mountaintop proposal. Their creative partnership has frequently intertwined with their romance, notably when Finneas wrote his track “Claudia” within hours of their first meeting, and when Sulewski starred in and directed the music video for his 2022 single “Mona Lisa, Mona Lisa.”
A Weekend Defined by Custom Oscar de la Renta Fashion
The wardrobe progression included a satin statuesque white backless gown for the rehearsal dinner, a primary ceremony ball gown, a columnar reception dress featuring a feathered peplum, and an after-party ensemble pairing a baby pink top with a structured grey bubble skirt.

The centerpiece of the weekend was the off-the-shoulder ceremony ball gown, which featured a drop-waist bodice, a pleated skirt, and an asymmetric scarf neckpiece. “We were putting it on, and I was saying, there’s something about this dress that just demands a moment of silence,” Sulewski told Vogue during her final fitting. The fittings included a surprise FaceTime call from Billie Eilish, who interrupted the session to admire the look, telling her future sister-in-law, “My God, I can’t believe it. You look like an angel. Sorry to be interrupting. Love you so much.”
From Dating App Beginnings to a Landmark Celebration
As the newlyweds transition into this next chapter, their union marks a major milestone for two prominent figures who have balanced individual creative empires with a deeply public yet grounded relationship. Sulewski continues her work as an actress, YouTuber, and the founder of CYKLAR Skincare, while Finneas maintains his status as a songwriter, producer, and solo artist.
With the ceremony concluded and the celebrations at San Ysidro Ranch wrapped up, the couple returns to everyday life supported by a tight-knit family and a creative community that has cheered them on since their initial swipe right.
