Selena Gomez Checked Into Rehab After Hanging Out With Justin Bieber

Selena Gomez needed a break.

The 21-year-old "Come & Get It" singer entered rehab at The Meadows recovery center in Arizona in January for a two-week stay, a rep for the star confirmed to the Daily News.

"Selena voluntarily spent time at Meadows but not for substance abuse," her rep said in a statement.

Her stint came shortly after the brunette beauty announced her tour cancelation in December, telling her fans that despite her decision, they are so important to her and she would "never want to disappoint them."

"It has become clear to me and those close to me that after many years of putting my work first," she continued.

"I need to spend some time on myself in order to be the best person I can be."

Radar Online was first to report the starlet's stay in rehab and a source told the gossip site that before she left she was "partying very hard," and had been "experimenting with marijuana and prescription drugs, including Xanax and Ambien."

"Her friends and family became increasingly worried that there might be a serious problem with Selena," another source alleged to Radar.

"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."

A source told TMZ that the pop star's choice to seek help had a lot to do with what she was exposed to when around ex-boyfriend Justin Bieber and his pals.

Gomez was last spotted hanging out with Bieber before entering The Meadows. The two were seen riding on Segways together through the "Baby" singer's California neighborhood in early January followed by a cozy Instagram upload from the Biebs.
