Selena spent 2 weeks at the recovery in Arizona
The 21-year-old was admitted to Dawn at The Meadows recovery centre - which treats people aged 18 to 26 years - in Arizona on January 5.
A representative for Selena – who has an off-off relationship with Justin Bieber – confirmed the report but says it was NOT related to substance abuse.
"Selena voluntarily spent time at Meadows but not for substance abuse," her rep said.
It comes after sources in US claim Selena 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.
“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."
The brunette beauty is now said to be doing well. A source said: "Selena is feeling much better. She’s feeling really positive, healthy and already getting back to work."
