Finneas O’Connell Marries Longtime Girlfriend Claudia Sulewski

SANTA BARBARA: (Showbiz Desk) – Musician and songwriter Finneas O’Connell has married his longtime girlfriend, YouTuber Claudia Sulewski, in a star-studded ceremony at the San Ysidro Ranch in Santa Barbara, California.

The couple exchanged vows on Saturday during an outdoor wedding attended by several high-profile celebrities.

Finneas’ sister, singer Billie Eilish, reportedly officiated the ceremony. Among the guests were Justin Bieber and Hailey Bieber, Dax Shepard, Kristen Bell, Nina Dobrev, Emma Chamberlain, Jason Sudeikis, Carter Gregory, Stassie Karanikolaou and Rachel Sennott.

Eilish’s boyfriend, actor Nat Wolff, was also present at the celebration.

Claudia Sulewski’s Wedding Looks

Sulewski wore several Oscar de la Renta creations throughout the wedding weekend.

Her standout look was an elegant off-the-shoulder ball gown featuring a drop-waist bodice. She completed the sophisticated ensemble with a scarf-style neckpiece.

During a final fitting ahead of the ceremony, Eilish shared her emotional reaction to the gown in an interview with Vogue, describing the dress as one that demanded a moment of silence.

A Love Story That Inspired Music

Finneas, 29, and Sulewski, 30, first connected on a dating app in 2018. The relationship quickly inspired the musician, who revealed in a 2019 BuzzFeed Celeb interview that he wrote the song “Claudia” just hours after meeting her in person.

Sulewski later became the inspiration behind another of Finneas’ songs, “Mona Lisa, Mona Lisa,” released in 2022. She also appeared in its music video.

The couple announced their engagement in September 2025 following a romantic mountaintop date.

Sharing the news on social media, they posted the message “forever and ever 9.22”, marking another milestone in their relationship.

After years together, Finneas and Sulewski have now officially begun their married life.
