She may have been a teen princess but Selena Gomez is showing is now a grown up a fashion queen.

The 20-year-old has channeled her inner sexy rock chick in a fun and flirty advertising campaign for her new clothing range.

The singer is adding designer to her long list of talents with Adidas giving the Disney star her very own line.

Dubbed Neo, the street wear range, which includes shoes and clothing, is aimed at teenage girls.

Despite the rock chick look designed for teens, Selena made sure to separate herself from her pop princess image.

For the advertising campaign Selena wore her voluminous brown locks in a teased messy bedhead style.

In one image, the singer pulls her messy hair in front of her face staring down the lens of the camera confidently, looking as if she is ready to head to a rock gig.

Making sure to keep her look edgy, the 20-year-old wore dark smoky eyes and smudge pink lipstick over her bee stung lips.

For the campaign Selena runs a muck inside a design warehouse climbing up ladders, jumping on couches and rolling on her inspiration sketches while screaming on the floor.

While she strikes various poses, the star only models two outfits from her collection.

In one, The Come And Get It songstress flashes some serious leg in a pair of tiny denim rolled up studded shorts.

Completing the look Selena also dons a pink T-shirt, studded black platform sneakers and, of course, keeping with the rock chick aesthetic a leather jacket.

For her second look the Monte Carlo star picked a more covered up outfit wearing black leggings with stud embellishment and a white T-shirt emblazoned with the words ‘Get out there’ over which she added a denim vest.

The vest is one of Selena’s favourites as it is tough but still feminine and ‘perfect for a lunch date with friends’ she said.

The two looks are just a tiny sample of the extensive 53-piece collection which the singer launched in Berlin, Germany on Monday.

The Neo range Selena says is about having confidence and fun with you look.

Launching the line she said: ‘I love playing around with fashion and like clothes that are fun, easy to wear and comfortable.

‘My collection has a rock chic theme and it’s confident, rebellious and fun.

‘It’s also a little bit darker and I think it encourages girls to put their own stamp on their individuality and show confidence in what they are wearing.’
