Pregnant Hailey Bieber Shows Off Baby Bump in New Behind-the-Scenes Pic from Pregnancy Announcement Video

Hailey Baldwin Bieber is sharing a new glimpse at her growing baby bump.

On Friday, May 10, the mom-to-be, 27, posted a new photo of herself in the Saint Laurent by Anthony Vaccarello white lace dress she wore in the pregnancy announcement and vow renewal video and photos she and her husband Justin Bieber posted the day before.

Hailey — who is expecting her first child with Justin, 30, — appeared in the Instagram Stories snap with her baby bump highlighted in the form-fitting white off-the-shoulder lace gown with a matching headpiece, which also doubled as a veil, as she stood on a balcony overlooking palm trees and the sea.

In the photo, which was captioned with the heart hands emoji and sparkles, Hailey smiled while staring off to the side as she rested her hands just above her baby bump. Although the Biebers' May 9 vow renewal video was filmed outdoors, Hailey's latest snap appeared to have been taken just before, or after, it was filmed.

The Rhode founder’s bridal look in the photo was first shown in that video, and the accompanying photos, which Hailey and Justin posted on Instagram. The carousel of footage and pics showed the couple — who married in 2018 — renewing their wedding vows and gave fans the several glimpses of Hailey's baby bump.

Shortly after the Biebers shared that they are expecting their first baby together, Hailey’s rep confirmed to PEOPLE that the model is just over six months pregnant. Justin's mother, Mallette, 49, also shared, in a comment on Stephen Baldwin's Instagram post the same day, that the couple are not having twins. 

In their pregnancy announcement video, Hailey and Justin kissed as they stood on a field together during their vow renewals. In another shot, Justin placed his arms around his wife’s stomach as he stood behind her, while the pair showed off their matching wedding rings.

Hailey was also seen posing with her baby bump solo in other snaps on the carousel, which also featured photos of her and Justin kissing and both cradling her growing baby bump. 

Hailey and Justin’s vow renewal comes ahead of their sixth wedding anniversary this September. And while the couple have been open about their desire to become parents together, they decided to keep the news of them expecting their first child a secret for as long as possible — telling only their family and friends “early on.”

A source told PEOPLE, "When they found out that Hailey was pregnant, it was just the best day for them. They have both been very emotional about it. They feel so blessed. They've also felt very protective of the baby from the moment they found out."

"They shared with family and close friends early on. It was important for them to keep it quiet and just enjoy for as long as possible before they publicly confirmed though,” the source continued.

"They asked their friends to not share until they were ready to announce."
