Demi Lovato has opened up about why she tried cocaine.

The singer, who checked into rehab in 2010 for an eating disorder, confessed that she often felt depressed when she was alone.

"It's something I don't really want to talk about," Lovato told Fabulous.

"What I can say is that I was depressed," she continued. "I would come off stage in front of 18,000 people and suddenly be alone in a hotel room. I'd come crashing down and would try to find a way to recreate that feeling, to stay 'up'."

Lovato previously admitted that she considered giving up her career after going to rehab.

She has said that she will not return to films until she has completely recovered.
