Singer Finneas O’Connell and YouTuber and actress Claudia Sulewski have tied the knot.
The US singer-songwriter and musician, who goes by his stage name Finneas, is known for co-writing and producing music with his sister Billie Eilish, including Bad Guy, Birds Of A Feather and What Was I Made For.
Finneas and Sulewski got married at a ceremony on Saturday in Montecito, California, after being together for eight years.
Ahead of the big day, Sulewski told Vogue that she had four dresses for the weekend – for the rehearsal dinner, the ceremony, reception and finally the after-party – that were all custom-made by American fashion house Oscar de la Renta.
The first was a satin gown with a deep draping neckline that extended to the lower back.
The ceremony dress was a dramatic ivory silk ballgown with a drop-waist bodice and pleated skirt. The dress was completed with a pleated scarf neckpiece that extended to the length of the train.
She said: “We were putting it on, and I was saying, there’s something about this dress that just demands a moment of silence.”
The YouTuber also wore a structured cady gown with a structured feathered waist.
Sulewski said the dress felt so “grown up in this sexy wifey way” while also being celebratory.
The final look was a 2000s piece featuring a pink boat neck top paired with a grey draped bubble skirt and matching grey heels.
The couple got engaged in September 2025.
The award-winning music producer has picked up two Academy Awards, both for best original song, as well as 11 Grammys, including record of the year in 2020 with Bad Guy and three prizes for song of the year in 2020, 2024 and 2026.
He also creates music under his stage name Finneas and with the group The Favours, which is made up of him and singer-songwriter Ashe.
Sulewski is known for appearing in Shrinking and 2022’s I Love My Dad.
She is also the founder of skincare brand Cyklar.
