Hailey Bieber Dresses Up Her Bump in Bridal-Like Sheer Gown for Pregnancy Reveal and Vow Renewal with Justin

The couple, who are expecting their first child together, looked effortlessly cool in Saint Laurent looks to renew their vows in Hawaii

Hailey Bieber's first public maternity style moment was a major one!

On May 9, the Rhode founder, 27, and her husband Justin Bieber, 30, shared a joint Instagram post containing a video of their romantic vow renewal as well as photos revealing Hailey’s baby bump. A rep for the model confirms to PEOPLE that she's six months pregnant.

For the occasion, the soon-to-be mom wore a dreamy Saint Laurent by Anthony Vaccarello white lace dress. The custom, floor-length design featured an off-the-shoulder silhouette and sheer detailing.

She topped off the elegant design with a bespoke lace head scarf that covered her hair and wrapped around her neck. The headpiece also doubled as a long veil that draped over her shoulders and cascaded down her back. She wore black Saint Laurent sunglasses too, which gave the ensemble an Old Hollywood vibe.

Leaving no detail out, Hailey's nails were painted in a pearlescent hue similar to her viral “glazed donut” manicure. Although she’s tried many iterations in the past, from neon to blush pink, it seems like she always finds her way back to her favorite opalescent chrome mani, which can be seen in a close-up photo of her and Justin’s sleek, but sparkly, wedding rings.

The “Peaches” singer also wore a look by Saint Laurent. He decided to channel his laid-back aesthetic in a fleece jacket, a button-up shirt and trousers. He topped off the 'fit with a baseball cap worn backwards because, after all, that is his signature style.

Many of the sweet snapshots of the couple’s intimate ceremony show Hailey cradling her bump. The vintage-style video also shows them sharing a kiss with mountains in the background.

Friends Kendall Jenner, Bella Hadid, Kourtney Kardashian, Kaia Gerber, Lori Harvey and Sofia Richie Grange shared their well-wishes in the comments.

The couple secretly tied the knot at a New York City courthouse in 2018, two months after they got engaged. Hailey and Justin then threw an official wedding ceremony one year later, celebrating with family and friends, exchanging vows and Tiffany wedding bands in Bluffton, South Carolina.

Hailey wore three wedding dresses on the day, including one designed by her friend, the late designer Virgil Abloh, who died in November 2021. The backless gown was covered in floral lace and had the words "Wedding Dress" spelled out in pearls along the back. She topped off the look with a veil embroidered with the phrase, "Till Death Do Us Part.” She slipped into a  custom Rich & Russo silk gown and then a Vera Wang design for the reception.

Despite attending Coachella in April, the couple have been hush-hush about their exciting news.

In October, Hailey addressed rumors about her being pregnant, commenting on whether or not they affected her. "There is something that's disheartening about, damn, I can't be bloated one time and not be pregnant? It would be a lie if I was like, 'Oh yeah, I don't give a s---.'"

"When there comes a day that that is true, you, you as in the internet, will be the last to know," she candidly added.
