Billie Eilish's role at her brother Finneas' wedding
And it looks like Finneas' younger sister and most frequent collaborator Billie Eilish had the task of officiating the ceremony, going full regal glam for the occasion.
The Grammy-winning singer was dressed in a fitted off-the-shoulder olive green gown with a structured bodice paired with a skirt that pooled at the waist. Her brunette locks were styled into a shoulder-length bob.
Claudia Sulewski's four wedding looks
Of course, the real stunner of the day was Claudia herself, who had four custom Oscar de la Renta wedding looks prepared for the weekend, the main event being a beautiful silk white ballgown featuring a dropped waist bodice and a grand pleated skirt, paired with an asymmetric scarf neckpiece — with pockets!
Claudia showed off her many wedding looks to Vogue, which included a gorgeous satin statuesque white backless gown for the rehearsal dinner, a columnar white gown with feathered peplum for the reception, and then an after-party dress featuring a baby pink top with a structured grey bubble skirt and matching heels.

Billie and Finneas' mother Maggie Baird, who was at the final fitting with Claudia, dialed the "Birds of a Feather" singer in to take a look as well, with Billie saying via FaceTime: "My God, I can't believe it. You look like an angel. Sorry to be interrupting. Love you so much!"

"Finneas hasn't seen any of these dresses, but since we're doing our first dance in this dress, I've had to be very vague about certain limitations – the ways in which he can lift me, for example," she noted. "We want to keep it intact, so I've just been like: there's an obstacle," referring to the feather peplum detailing.

As for the wedding itself, the photos indicate it was quite the star-studded affair. Apart from family and friends, some of the attendees pictured include Billie's boyfriend Nat Wolff, Justin and Hailey Bieber, Rachel Sennott, Emma Chamberlain, Jason Sudeikis, Nina Dobrev, Kristen Bell and Dax Shepard, plus Claudia's closest friends Dru MacDonald and Rebecca Black.
