Hailey Bieber is expecting her first child with husband Justin Bieber – with the pair revealing their baby joy during a surprise vow renewal in Hawaii.

The model, 27, announced her pregnancy joy with singer Justin, 30, with a beautiful video showing her debuting her bump in a custom Saint Laurent lace wedding dress by Anthony Vaccarello, paired with a flowing veil.

The star and the Baby hitmaker – who recently sparked concern with a crying selfie – shared a sweet kiss as they celebrated their news during their outdoor ceremony – with Hailey sporting a new diamond ring.

Justin – who was casually clad in a backwards cap, bomber jacket and jeans – was seen filming his bride cradling her bump – with the video set to a new track by the Grammy winner.

The couple have been married since September 2018.

TMZ reports that Hailey is more than six months pregnant. 

Kendall Jenner quickly took to the comment section of Hailey’s post to declare: ‘ahhhh here come the tears again.’

Kim Kardashian wrote: ‘I love you guys sooooo much!!!!’ while Chrissy Teigen penned: ‘EEEEEEEEEEEEEEEEEEEEEEEEE!!!!!! You are going to be an amazing amazing mommy oh boy get ready!!! So exciting so happy for you both!!’

Kylie Jenner wrote: ‘i love you guys!!!! ahhhhhhhh’ while mom Kris Jenner wrote: ‘We are so so excited can’t wait can’t wait what a blessing!!!!!’

Justin and Hailey were first introduced in 2009 by Hailey’s father Stephen Baldwin at the premiere of Justin’s documentary Never Say Never.

The pair then had a brief fling in 2016 amid a break in his on/off decade-long romance with Selena Gomez.

When he and the Disney Channel alum, 31, finally called it quits for good in May 2018, Justin fell into Hailey’s arms and they’ve been attached at the hip since.

The pair have spoken candidly about their relationship over the years — including their ‘really tough’ first year of marriage.

Speaking to GQ in 2021, Justin revealed that his and Hailey’s initial difficulties stemmed from ‘trauma’ and ‘just lack of trust.’
