Justin Bieber doesn't often confirm his romances on social media – so he must be feeling pretty smitten with new rumoured girlfriend Audreyana Michelle, after sharing a snap of the pair walking through Hollywood Hills yesterday (24 July).

Without a caption, the Despacito singer left his 90m followers to speculate as he posed topless alongside Audreyana, who wore a casual outfit of a white T-shirt, black bomber jacket and black jeans.

So who exactly is Justin Bieber's new lady?

She's a 17-year-old internationally signed model and Instagram star who has modelled for both Kylie Jenner and Khloe Kardashian's brands – and has caught the eye of the mass public since being spotted with the singer.

The teen who is signed to the likes of Freedom Models LA and Premier Models London – has a fast-growing social media following with 357K Instagram fans and receives thousands of 'likes' and comments on her snaps.

She seems like a fun-loving normal girl who loves make-up, healthy food, girly fashion, travelling and taking a bunch of selfies. Audreyana claims to be of mixed heritage as a mix of white American, African American and Native American, and was born in Oklahoma City but currently divides her time between Arizona and Los Angeles.

She once described her personality as "outgoing, considerate, and fun" in an interview with Frankiesbikinis.com and her modelling career only took off after her mother put her forward at an agency.

She said: "My mom submitted me to an agency in the summer 2016 and it took off from there! I've always wanted to model and to be able to share my love of fashion through photography. I also think it's great to inspire other girls/guys that they can follow their dreams no matter where they've come from!"

Despite being just 17, Audreyana has already modelled for the likes of Frankies Bikinis, Pac Sun and LPA. Introducing her more to the celebrity circle, she has modelled for Khloe Kardashian's jeans line Good American along with Kylie Jenner's highly sought-after cosmetic range.

Audreyana hasn't yet posted a snap of herself with Bieber, but seems to be in a happy place as her latest snap was captioned with: "it's a good day to have a good day".

One fan likened her to Bieber's ex-girlfriends, commenting: "this is Justin's new beau which is sad bc she looks like a cross between Selena and Sophia Richie".

While another put: "You are beautiful. Don't listen to the stupid haters☺️❤️""
