Congratulations are in order for Finneas and Claudia Sulewski!

The couple married today in a lush outdoor ceremony that took place in Montecito, California. Finneas’s younger sister, Billie Eilish, officiated the ceremony, according to photos published by TMZ.

Sulewski, a beauty content creator who founded skincare brand Cyklar, wore four looks over the course of her wedding weekend, all of which were custom-made by Oscar de la Renta. To walk down the aisle, she wore a strapless drop-waist ball gown with a neck scarf.

Among the pictured guests were stars like Hailey and Justin Bieber, Rachel Sennott, Jason Sudeikis, Kristen Bell, Dax Shepard, and Emma Chamberlain. Eilish’s boyfriend, Nat Wolff, was also reportedly in attendance.

Finneas and Sulewski have been dating since 2018, when they first met each other through a dating app. The two announced their engagement in September 2025.

In a recent interview with Harper’s Bazaar, Sulewski talked about how wedding planning has shaken up her typical routines.

“I’ve been so busy planning a wedding and its surrounding events this year that I’ve really been off my reading game, which I hate to admit, but it’s true!” Sulewski said. She also talked about starting this next chapter of her life: “My current podcast fixation is listening to shows or episodes about pregnancy, giving birth, and egg and sperm quality. I’m fully diving into the research. I’m still far out from that chapter of my life, but I love learning about the human body and the different ways that we can optimize our health before taking that next step.”
