Hailey Bieber is pregnant, expecting first baby with Justin Bieber

The rumours are true – Hailey Bieber is expecting her first child with baby daddy, Justin Bieber.

The model, 27 and singer, 30, took to Instagram last night to share the announcement on Instagram with a video of the couple renewing their vows in Hawaii alongside a string of photos of Hailey cradling her baby bump.

In the post, the Rhode founder donned a white lace dress by Saint Laurent, designed by Anthony Vaccarello, elegantly showcasing her blossoming baby bump. Completing her ensemble, she paired the custom floor-length dress with a bespoke lace headscarf that also functioned as a veil, complemented by black Saint Laurent sunglasses.

According to PEOPLE, a source revealed that the day the expectant parents learned about their first baby together was described as "simply the best day for them."

"Everyone is excited for them," the source says. "They will be great parents, and Justin will be super involved. This will be the next important project for him. He’s so excited to raise his baby. They have a name that they think is perfect. They’re also starting to decorate a nursery. They can’t wait to meet the baby."

"They have both been very emotional about it. They feel so blessed," the source says. "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 very important for them to keep it quiet and just enjoy [it] for as long as possible before they publicly confirmed."

The couple was spotted in Hawaii a couple of weeks ago, during which Hailey wore a flowing dress concealing her typically slender figure, prompting online speculation about a possible pregnancy.

Entertainment outlet, TMZ, citing "sources with direct knowledge," reported that the pregnancy had progressed beyond six months.
