Hailey Bieber looked sensational as she joined husband Justin Bieber for an ultra-glamorous date night at one of the summer's most star-studded weddings.
The 29-year-old Rhode founder was among the famous faces who watched Grammy-winning producer Finneas O'Connell marry his longtime love Claudia Sulewski in Montecito, California, on Saturday, August 29.
Hailey certainly understood the garden wedding dress code, turning heads in a vibrant citrus-green halter gown that featured an ultra-plunging neckline and a dramatic, floor-sweeping skirt.
The striking design featured ruched triangle cups held in place by a slender halterneck strap, before falling into a fitted bodice and voluminous skirt that created a romantic silhouette as she walked.

Beauty-wise, the mom-of-one swept her brunette locks into a sleek updo with a subtle center part and opted for glowing rosy makeup and a soft pink lip.
Justin, 32, kept things classic alongside his wife in a black suit and tie worn with a crisp white shirt, dark sunglasses and his signature hoop earring.
Hailey and Justin enjoy glamorous parents' night out
The wedding offered Hailey and Justin a rare glamorous night out together just one week after they celebrated their son Jack Blues' second birthday.

The couple, who welcomed Jack on August 22, 2024, have largely kept their little boy out of the public eye, sharing occasional glimpses without showing his face.
The Biebers appeared to enjoy catching up with friends at Saturday's celebrations, with Hailey photographed chatting to the groom's younger sister Billie Eilish, who had perhaps the most important role of anyone at the wedding.
The 24-year-old Birds of a Feather singer officiated her brother's ceremony, wearing an olive-green off-the-shoulder corseted gown with a sweeping satin skirt.
Billie arrived with boyfriend Nat Wolff, while other guests included Nina Dobrev, Kristen Bell and Dax Shepard, Emma Chamberlain, Jason Sudeikis, Rachel Sennott, Rebecca Black, Devon Lee Carlson and Stassie Karanikolaou.
Inside Finneas and Claudia's romantic wedding
The celebrations took place at the luxurious San Ysidro Ranch in the foothills of Montecito, where Finneas, 29, and Claudia, 30, exchanged vows after eight years together.

Claudia went all out for her bridal wardrobe, working with Oscar de la Renta to create four custom looks for the weekend.
Her main ceremony gown was an ivory silk-faille ballgown with a dramatic drop-waist bodice, structured pleated skirt and an asymmetric scarf detail that extended down the train.
"There's something about this dress that just demands a moment of silence," Claudia told Vogue ahead of the ceremony.
She also wore a liquid satin rehearsal dinner gown, a sculptural reception dress incorporating upcycled feathers and a playful pink and dove-grey after-party ensemble inspired by Oscar de la Renta's early-2000s collections.
An eight-year love story
Finneas and Claudia's wedding was the culmination of a romance that began on a dating app in 2018.
The connection was apparently instantaneous. Finneas was so smitten that he began writing his song Claudia the night they met and finished it the following day.

After seven years together, Finneas proposed during a romantic mountaintop date in September 2025, presenting Claudia with a cushion-cut diamond ring.
He later admitted that despite knowing Claudia was the person he wanted to marry, orchestrating the surprise left him lying awake at night worrying about getting every detail right.
For Hailey and Justin, meanwhile, the romantic celebration came during a particularly family-focused period.
The pair celebrated their seventh wedding anniversary last September and have spoken increasingly about how becoming parents has transformed their lives.
