Hailey Bieber was unveiled as one of the four famous faces of YSL Beauty’s Libre Flowers and Flames fragrance.

The Rhode Beauty founder – who is expecting her first child with husband Justin Bieber, 30  – shared two photos from the instantly iconic campaign for her 52.9 million Instagram followers.

In one photo, Hailey, 27, looked radiant in a close up of her holding the perfume bottle while wearing a heavy gold link necklace.

Her brown hair was parted on the side and swept off her face while her makeup was natural featuring rosy cheeks and a pink lip color.

In the second image, the model lounged on a couch in a long-sleeved, boat-neck black top that allowed some of her growing baby bump to show with a slinky black skirt.

The niece of Alec Baldwin believes fragrance can transport you.

‘A scent can take you right back to a certain time in your life, or a certain person in your life,’ she said in an interview with Vogue.

‘I’ve gone back to scents that I wore 10 years ago just for the pure nostalgia of it. I have a few scents that I’ve brought back years later after not wearing it and it triggers so many memories for me.’

And Hailey is certainly entering a new phase of her life with a baby on the way so she’s turned to a new fragrance: YSL Beauty’s Libre Flowers and Flame.

‘There is a sexiness to the fragrance, while still feeling very elegant and chic,’ she told the outlet. ‘That is exactly how I feel when I wear it.’

As Vogue explains it: ‘This interpretation of the Libre fragrance (there are six in total) spins the original juice into something more gourmand with notes of coco-palm tree, lily, orange blossom, and vanilla.

‘Bieber is the opening chapter of YSL Beauty and Mitchell’s Flowers & Flames series, which will feature three other trailblazing women in the weeks to come.’

A press release provided to DailyMail.com stated: ‘This new project brings together four talents; a group of dynamic, resilient women, who dare to live free of societal rules and expectations, amongst the current landscape.

‘Each one of them is more than just a public figure, or a social media handle. The LIBRE voices are each trailblazers for the future generation of women.

‘They embody the LIBRE spirit and are strong feminine voices who live a life free of bounds.’

‘I’m excited to be one of the women representing this generation and to be a part of this project during such a special time in my life. This project allows us to show the strengths in self-ownership, confidence, and diversity, and I am very happy to be a part of it,’ Hailey explained.
