Hailey Bieber shared modeling pictures from when she was four months pregnant.

The 27-year-old recently posted a photo of herself from her YSL campaign in which she reveals she was hiding a teeny tiny secret under her chic ensemble.

Hailey captioned her Monday morning Instagram Story, ‘Shot this 4 months preggy with little bean in my belly.’

The Rhode founder rocked a beige, strapless jumpsuit with a belt wrapped around her waist.

Hailey accessorized with a black YSL bag and bangle bracelets as she gazed into the camera. She finished off her look with closed, pointed-toe pumps.

The model, who is expecting her first child with husband Justin Bieber, continues to showcase her growing bump on social media

A close-up shot on her page showed the skincare mogul wearing massive silver drop earrings and her signature YSL black shades.

‘Summer 24 shot by @graysorrenti @anthonyvaccarello,’ she wrote beneath the images.

Hailey’s photoshoot comes on the heels of her getaway to Tokyo, Japan, over Memorial Day weekend with her husband Justin Bieber.

Hailey put her bump on full display in a cropped white t-shirt and matching white shorts. Her look came together with a green, white and orange cardigan, striped bucket hat and white sneakers.

Justin kept it casual in an oversized olive green button-down shirt, knee-length shorts, and slippers.

The couple, who tied the knot in 2018, announced they are expecting their first child in a sweet video montage posted to Instagram, capturing their Hawaii vow renewal.

The footage showed a pregnant Hailey dressed in a lace Saint Laurent dress and flowing veil, posing for maternity photos in a field while the Baby singer lovingly kissed his bride.

Since sharing the news, the supermodel has continued to give updates, calling the baby a ‘little cherry blossom’ and revealing her pregnancy cravings.

‘Currently my biggest craving,’ Hailey wrote on her Instagram Story in May. ‘Egg salad on top of a pickle with hot sauce, and no you’re not allowed to judge.’

Meanwhile, it’s safe to say the Peaches artist is just as excited to become a father.

Justin posted snaps of Hailey holding her belly to his Instagram page, simply writing, ‘They wish baby, they wish.’

These days, Hailey is back with her glam videos, recently sharing a tutorial for ‘My Peachy Beachy Summer Makeup’.

The influencer – whose hottest trends include glazed doughnut nails – has spilled the secrets of her makeup look for the hotter months.

And Bieber posted this selfie from inside her closet

In a YouTube video, Hailey shared: ‘It’s so glowy and moisturizing and good for the skin barrier without being heavy.’

The pregnant beauty used the Peptide Glazing Fluid, Dolce Glow’s Contour Self-Tanning Sculpt and Glow, Hourglass’ Concealer, Hydrating Skin Tint and Translucent Powder.

She then applied her peachy shades of blush.

Not revealing the brand, suggesting it’s an unreleased Rhode product, Hailey said: ‘I’m gonna go in with this sunburnt bronzy terracotta color first.’

‘The other color I’m going in with has a pinky-orange color.’

Meanwhile, Hailey recently revealed that Kate Moss will always be her beauty ‘muse’.

Asked who is on her beauty mood board, she told Harper’s Bazaar magazine: ‘I am constantly saving photos of Kate Moss. There’s something that I feel is so magnetic about her and her beauty.’

Hailey added, ‘She has transcended multiple periods of time.’

‘I just love the unevenness of her look,’ she continued. ‘You know, so effortless, so carefree.’

The couple renewed their vows in an intimate ceremony in Hawaii, while simultaneously sharing their baby news

And it doesn’t seem like that is going to stop anytime soon. ‘She’s forever going to be a muse for sure.’

But Hailey also finds it ‘flattering’ that she’s a beauty inspiration to other people.

Asked how it feels to be a fixture on so many other people’s mood boards, she replied: ‘It’s very flattering. To be able to connect with other people through beauty or clothing or hair, whatever it may be, is really fun.’

Adding, ‘I’ve really enjoyed submerging myself into this beauty community.’

‘There are so many amazing people on TikTok and Instagram,’ she told the outlet, ‘and so many amazing creators that I’ve been able to meet and to talk to.’

‘Even just watching their videos to see how they use their creativity and their point of view,’ she concluded, ‘has impacted me in a lot of ways.’
