She has just had her new grown-up image put on show in her leaked music video for Slow Down.

And it looks like Selena Gomez is continuing to trim and perfect her look as she was spotted heading out of a West Hollywood salon on Friday with a fresh new 'do.

The 20-year-old on-again-off-again girlfriend of Justin Bieber was looking casually chic as she sported a tank that interestingly read 'out of control'.

Selena opted for a comfortable pair of grey tracksuit bottoms for her long haul in the salon chair, and teamed it with the cute white printed tank.

The Disney star gave her ensemble a cool retro edge with a rounded pair of sunglasses.

A dash of red lipstick and high-top platform trainers ensured a sexy look was maintained despite her tomboyish ensemble.

Looking fresh: the 20-year-old star managed to nail the casual-chic look as she teamed a cute green leather handbag with a laid-back green plaid shirt slung around her waist

Around her waist, the brunette songstress wore the same casual green plaid shirt she's been spotted with often recently.

A matching green handbag made the star look effortlessly stylish as she left the salon with sleek new locks, freshly styled and straightened.

Selena clutched her phone at all times and given recent speculation on her on-again-off-again relationship with Justin Bieber, perhaps the pair were communicating.

Justin brought two girls back to his New York hotel on Tuesday night after partying at 1 Oak nightclub, according to the New York Post.

Following his outing at the popular venue, Justin then apparently moved onto his hotel where he continued to party alongside two girls.

But if the young pop star managed to catch Selena's leaked new music video for her new single Slow Down, he'd surely be second-guessing his actions.

The stills show the young singer and actress in a far more mature light, sashaying in a car before hitting a dance floor in jaw-dropping attire.
