Hailey Bieber puts on a busty display in a plunging jumpsuit for a glamorous Saint Laurent campaign

Hailey Bieber oozed glamour in a jumpsuit with a plunging necklace that showed off her ample cleavage as she gazed at the camera for a sexy Saint Laurent campaign.

While modeling garments from the French fashion house, including a faux fur jacket, the 25-year-old supermodel can be seen laying on her side as she shot a smoldering stare at the camera.

In the images, posted to her Instagram on Tuesday, the Rhode founder positioned her lips into a subtle, sultry pout as she rested her head on the palm of her hand.

In addition to flashing quite a bit of underboob, the five-foot-seven beauty bared plenty of her décolletage and part of her incredibly toned midriff. 

Her wavy, light brown hair was styled in soft, tousled waves, which cascaded past her shoulders. 

The former ballet dancer’s post comes just a day after her husband Justin Bieber shared a sweet snap of them kissing their pal Jason Kennedy’s newborn son Ryver.

While ringing in the Fourth of July with the adorable infant, the 28-year-old pop star and model, 25, appeared to have a case of baby fever as they planted kisses on both the child’s cheeks.

In an image, posted to the singer’s Instagram account on Monday, Justin can be seen sporting a backwards olive green baseball cap and striped button-down over a plain white t-shirt.

As Hailey cradled the baby boy, who Kennedy shares with Lauren Scruggs, Hailey was a natural at keeping him calm and at ease.

In April, Justin shared a photo snugging with Ryver, who he refers to as his nephew, with a sweet caption vowing to protect the baby ‘for life.’ 

During an interview with Access Hollywood in May, Justin gushed he has always had ‘a love for kids.’

‘It’s purity – you look at them, it’s like, it’s a miracle,’ he explained.

Earlier this year, Hailey spoke about her eventual plans to expand her family while telling WSJ Magazine: ‘I think ideally in the next couple of years we would try. But there’s a reason they call it try, right?’

‘You don’t know how long that process is every going to take. Definitely no kids this year, that would be a little hectic, I think,’ Hailey added.

‘There’s this thing that happens for women when you get married. Everybody assumes it’s: ‘First comes love, then comes marriage, then comes the baby,’ she explained.

‘Well, what about the things I want to accomplish in my business? I think I had it ingrained in my head that I was going to want to have kids right away and I was going to have kids super, super young. Then I turned 25 and I’m like, I’m still super, super young!’

They tied the knot in an extravagant wedding in South Carolina on September 30, 2019 at the Montage Palmetto Bluff resort in front of 154 guests that included Kendall and Kylie Jenner.

Hailey said about married life with Justin: ‘Behind closed doors, we’re two really normal people that just have not-normal lifestyles and careers. I think given the magnitude of Justin’s career, he’s a very normal person, and I don’t think that always happens.’

After their brief split in 2016, Hailey said she felt like an outcast at her church she attended at the time: ‘There were a lot of people in the church world that made me feel very outcast. When did church become a social club? That was such a bad feeling.’
