Billie Eilish took on a meaningful role during her brother Finneas O’Connell and Claudia Sulewski’s nuptials.
Adding an extra touch of love to the couple’s major milestone, the BIRDS OF A FEATHER hitmaker officiated the wedding.
On Saturday, August 29, the music producer tied the knot with his longtime girlfriend at San Ysidro Ranch in Santa Barbara in an intimate outdoor ceremony surrounded by family, friends, and their dogs Peaches and Moose.
On her big day, Sulewski, 30, donned four wedding weekend looks designed by Oscar de la Renta.
According to Vogue, one dress was for the rehearsal dinner, another for the ceremony, one for the first dance and reception, plus one for the after-party. Finneas, 29, meanwhile, wore a classic tuxedo.
Billie, 24, opted for a metallic olive-green off-the-shoulder full-length dress. The figure-fitting attire featured a draped/ruched bodice and waist.
Photos circulating online captured the Happier Than Ever songstress standing with the couple as she carried her special duty as an officiant.
She was also seen chatting with Hailey Bieber and other guests at the wedding.
Other celebrities in attendance included Nina Dobrev, Dax Shepard, Kristen Bell, Emma Chamberlain, Rachel Sennot, Stassie Karanikolaou, Jason Sudeikis and Carter Gregory.
Billie’s boyfriend, Nat Wolff as well as the Lovely singer’s childhood crush Justin Bieber was also in the attendance.
