Hailey Bieber has stripped down for one of her raunchiest photoshoots ever.

The model, 29, showed off her jaw-dropping physique in undergarments from Kim Kardashian's Skims line.

In one provocative photo, the skincare mogul risks a wardrobe malfunction by allowing her white bra to slip from her shoulders. 

In another image, Bieber flaunts her toned backside in a nude thong. 

Fans were completely stunned in the comments section, with reactions ranging from lavish praise to total shock. 

'Hailey’s face card never ever declines,' gushed one, while a second wrote, 'She is so insanely hot, I will never buy Skims though.'

Bieber's husband Justin even posted a racy photo from the campaign to his account, with one fan writing, 'Justin showing off his wife... A REAL HUSBAND.'

'Hailey Bieber is selling the same basic girl aesthetic for more than a decade. I feel like I’ve been seeing the same photo of her regardless of what she is promoting,' complained another.

'Another nepo baby with an overinflated sense of self worth,' added another. 

Some critics even accused Bieber of airbrushing the images, with one commenting, 'Those pictures are so heavily photoshopped the original model could have been your mother. 

It comes after Bieber was forced to deny rumors she underwent a Brazilian Butt Lift, saying she made a 'commitment' to herself not to alter her appearance with the help of a doctor.

In an interview with Allure magazine last year, the mother-of-one credited her fit physique to working out four times a week. 

She specifically cited lunges as the exercise that best help tone her bottom.

Bieber's beauty brand Rhode is valued at approximately $1 billion as of May 2025, following an acquisition deal by elf Beauty.

She told Time magazine that she drew a firm 'line in the sand' before agreeing to the blockbuster deal that transformed her from celebrity founder into one of the beauty industry's most closely watched entrepreneurs.

She reflected on the company's rapid rise and her determination to maintain what she described as an accessible approach to skincare following its acquisition by elf Beauty.

The deal – one of the most talked-about celebrity beauty transactions of the past year – further cemented her status as a major force in the cosmetics industry amid continuing fascination with her marriage to Justin.

In her Time magazine profile, she admitted to 'manifesting' a target sale price of $1 billion for her brand.

'I'm somebody who really believes in, like, what you say out loud is very important. Our words are important,' she said.

The entrepreneur explained she set a clear financial target before entering negotiations around the company's future.

'I was like, "It has to be this number. I will not go for less." It was a goal.' 

Following the acquisition, Bieber stepped into the roles of chief creative officer and head of innovation, maintaining direct involvement in the brand she launched as part of the growing wave of celebrity-backed skincare and beauty labels.

Rhode has become one of the most visible names in the market through its minimalist branding, viral lip treatments and aggressive social media marketing strategies.
