Arizona model spotted hiking with Justin Bieber

Justin Bieber was photographed last weekend by paparazzi taking a hike in Los Angeles with an Arizona model who's left some people wondering who she is. 

Well, Beliebers, worry no more. 

The Canadian singer shared a snapshot of him and the model with his 90 million followers on Instagram Sunday without comment. As of Wednesday, the post has received more than 2.3 million likes. 

The young woman sporting a black-and-white athleisure ensemble, identified by photographers as Audreyana Michelle, has remained mum about Bieber on her social media accounts.

According to her Twitter profile, Michelle moved to Arizona from Oklahoma City in July 2015. The following year she signed to the Scottsdale-based talent management company, The Agency Arizona.

Her test shots and development all occurred in the Valley and she has booked local clients including Spiritual Gangster, which designs yoga-inspired casual wear.

"She's a lovely, kindhearted and sweet young lady," said Agency Arizona agent Terri Camberlango.

Camberlango said Michelle is 18 years old and that the teen's "unique, beautiful" look helped her score representation in fashion hot spots that include Los Angeles, London and Miami. Though she is signed to the Freedom Models, NEXT and Premier Models agencies across the globe, the Agency Arizona remains her "mother agency" that manages her career. 

Camberlango said the model is consistently booked for work. She said the agency would not be commenting on the Bieber picture. 

In an interview with swimwear client Frankie's Bikinis, Michelle described herself as having an outgoing, considerate and fun personality with an "edgy style. 

"I've always wanted to model and to be able to share my love of fashion through photography," she said. "I also think its great to inspire other [girls and guys] that they can follow their dreams no matter where they've come from!"

Since signing, Michelle has garnered a staggering social media following, which totaled more than 300,000 followers well before her affiliation with Bieber. She also has more than 12 thousand Twitter followers.

There's even an "Audreyana News" Twitter account that dubs itself the "first and only source for daily news" on the model. The account shares photos and updates of her social media posts, paparazzi snapshots and bookings.

One thing's for certain: she's always on the go.

Bieber, however, is laying low after cancelling the 15 remaining performances of his Purpose World Tour due to "unforeseen circumstances."
