Selena Gomez went to rehab, so time for Justin Bieber to follow?

Selena Gomez went to rehab last month.

The 21-year-old star - who has an on/off relationship with Justin Bieber - was admitted to Dawn at The Meadows recovery centre in Arizona on January 5, and spent two weeks at the facility, which treats people aged 18 to 26 years old who are "struggling with emotional trauma, addiction or dual diagnosis concerns."

Her representative confirmed: "Selena voluntarily spent time at Meadows but not for substance abuse."

The former Disney child star was urged to seek help by those close to her amid concerns her partying was getting out of control.

One source told RadarOnline.com: "Her friends and family became increasingly worried that there might be a serious problem with Selena.

"Particularly, her parents. The partying was, at times, wild. They wanted to help her -- and they very much encouraged her to go to rehab. Others very close to her also urged her to seek professional help."

Another added: "It's important to remember that Selena had worked in Hollywood non-stop for six years. She was exhausted. Selena was smart enough to understand that she needed to take control of her life.

"It just got to a point where she needed to get out of Los Angeles, get away from 'the scene' and the pressures of Hollywood, to also get away from those who had, admittedly, become a bad influence on her.

"Selena needed to take the opportunity to work on herself. She realised she needed help."

Selena - who reportedly "regularly" smoked marijuana with Justin - had been due to tour Australia this month but cancelled the shows in order to "spend time on [herself]."

And the brunette beauty is now said to be doing well.

A source said: "Selena is now happy and very healthy and already getting back to work."

Selena Gomez blames Justin Bieber

Selena Gomez reportedly blames Justin Bieber for her problems.

The 21-year-old former Disney star checked into a rehab clinic for two weeks last month and she is said to think her on/off boyfriend - dubbed "that crazy boy" - is responsible for her problems because of the "excesses she was "exposed to by being around the 'Beauty and a Beat' hitmaker and his friends.

The 'Come and Get It' singer now regards Justin as a "bad influence" on her life.

A source told RadarOnline.com: "Selena came to understand just what a bad influence Justin had been on her life. Their relationship left her broken-hearted."

Another added: "I don't know whether Justin pushed her to drug use, but amongst their close knit group of friends, smoking was common place.

"Justin and Selena would smoke marijuana together regularly."

Following her completion of the two-week programme, Selena is not believed to be receiving outpatient help or in therapy.

The brunette beauty had been due to tour Australia this month but axed the shows in December in order to focus on herself.
