Hailey Bieber caresses her growing baby bump with husband Justin in sweet social media video as couple prepare for the birth of their first child

Hailey Bieber suggested her due date was just days away as she appeared in a new social media video with husband Justin on Sunday. 

The catwalk model, currently expecting her first child with Justin, revealed her enormous baby bump in an elegant white evening dress while attending an outdoor dinner party. 

Standing behind his wife, the Canadian pop star - dressed in a comparatively relaxed T-shirt and jeans - helps her caresses her growing belly as she strikes a pose.   

Days earlier, Justin, 30, took to Instagram with photos of himself snuggling up to his pregnant wife's exposed baby bump.

He snapped a selfie as her clung to the 28-year-old model's leg, showing off her growing belly.

The Canadian superstar had a gentle look on his face while rocking a backwards white cap and flaunting his scruffy beard. 

Although the famous couple has not yet confirmed how far along Hailey is, TMZ reported she was just over six months pregnant when they shared the news in May.

We can expect to see baby Bieber as early as August or September, as the couple comes up on six years of marriage.

In another snap, we see the pair sharing a romantic moment just inches away from each other face, while enjoying a pool day. 

He added an image of the pair cuddling in bed featuring the mother-to-be, makeup free.
