Hailey Bieber captivated onlookers with a striking green gown during a glamorous date night with husband Justin Bieber at a highly anticipated celebrity wedding. The event, held on Saturday, August 29, saw the Rhode founder join a constellation of famous faces to celebrate the marriage of Grammy-winning producer Finneas O’Connell and his long-time partner, Claudia Sulewski, in Montecito, California.
Hailey Bieber’s Standout Wedding Attire
Embracing the garden wedding theme, Hailey Bieber, 29, made a memorable entrance in a vibrant citrus-green halter dress. The gown featured a daringly deep plunging neckline and a dramatic, floor-sweeping skirt that exuded elegance. Its design included ruched triangle cups secured by a delicate halterneck strap, leading to a fitted bodice and a voluminous skirt that created a romantic silhouette.
Her accessories complemented the bold outfit: peep-toe heels, sparkling diamond earrings, and an olive-green Gucci handbag adorned with gold hardware. Even her beverage seemed coordinated, garnished with a lime wedge. For her beauty look, Bieber styled her brunette hair into a sleek updo with a neat center part, complemented by glowing, rosy makeup and a soft pink lip.
A Rare Parental Night Out for the Biebers
The wedding provided Hailey and Justin Bieber, 32, with a rare opportunity for a glamorous evening out together. This occasion followed closely on the heels of their son Jack Blues’ second birthday, celebrated just a week prior. Hailey marked the milestone by sharing a collection of personal memories from her pregnancy, including a previously unseen black-and-white photograph showcasing her baby bump.
The couple, who welcomed Jack on August 22, 2024, have generally maintained a private approach to sharing their son with the public, offering only occasional glimpses without revealing his face. At the wedding, the Biebers appeared to enjoy reconnecting with friends. Hailey was photographed in conversation with the groom’s sister, Billie Eilish, who played a significant role in the ceremony.
Billie Eilish’s Pivotal Role and Guest List
Billie Eilish, 24, had the distinguished honor of officiating her brother Finneas’s wedding ceremony. She chose an elegant olive-green, off-the-shoulder corseted gown paired with a sweeping satin skirt for the occasion. Eilish attended the event with her boyfriend, Nat Wolff. The star-studded guest list also included notable figures such as Nina Dobrev, Kristen Bell, Dax Shepard, Emma Chamberlain, Jason Sudeikis, Rachel Sennott, Rebecca Black, Devon Lee Carlson, and Stassie Karanikolaou, among others.
Inside Finneas and Claudia’s Romantic Nuptials
The wedding festivities took place at the picturesque San Ysidro Ranch, nestled in the Montecito foothills. Finneas, 29, and Claudia, 30, exchanged vows after an eight-year relationship. The couple thoughtfully included their rescue dogs, Peaches and Moose, in the ceremony as “flower dogs,” complete with matching silk bows fashioned from the same material as Claudia’s wedding gown.
Claudia Sulewski’s Multiple Bridal Ensembles
Claudia Sulewski embraced her bridal moment with an array of stunning outfits, collaborating with Oscar de la Renta for four distinct custom looks throughout the weekend. Her primary ceremony gown was a breathtaking ivory silk-faille ballgown. It featured a dramatic drop-waist bodice, a structured pleated skirt, and an asymmetrical scarf detail that elegantly extended into the train.
“There’s something about this dress that just demands a moment of silence,” Sulewski shared with Vogue prior to the ceremony. Beyond her main gown, she also wore a liquid satin dress for the rehearsal dinner, a sculptural reception dress incorporating upcycled feathers, and a playful pink and dove-grey ensemble for the after-party, inspired by Oscar de la Renta’s early 2000s collections.
An Eight-Year Love Story Culminates in Marriage
Finneas and Claudia’s wedding marked the beautiful culmination of a romance that began on a dating app in 2018. Their connection was reportedly immediate. Finneas was so captivated that he began composing his song “Claudia” on the very night they met, completing it the following day. Music has remained a central theme in their relationship, with Claudia later inspiring his 2022 track “Mona Lisa, Mona Lisa,” for which she also starred in and directed the music video.
After seven years together, Finneas proposed to Claudia during a romantic mountaintop excursion in September 2025, presenting her with a cushion-cut diamond ring. He later confessed that while he knew Claudia was the one he wanted to marry, the pressure of orchestrating a flawless surprise led to sleepless nights.
A Family-Focused Period for the Biebers
For Hailey and Justin Bieber, the wedding celebration occurred during a period of significant focus on their growing family. The couple celebrated their seventh wedding anniversary in September and have frequently spoken about the profound impact of parenthood on their lives.
