Demi Lovato responds to cocaine rumors

Demi Lovato has tackled long-running rumors she used cocaine while battling personal problems, admitting she was desperate to recreate the adrenaline rush of live concerts.

The Disney star sought professional help in 2010 for a number of issues, including an eating disorder, depression and self-harming.

Lovato has been brutally honest about her battles since leaving rehab, but has failed to respond to reports suggesting she was regularly using drugs before she faced her issues.

However, she has now opened up about the subject in a new interview with Fabulous magazine, and when asked if she took cocaine in her dark days, she says, "It's something I don't really want to talk about. What I can say is that I was depressed. 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 and find a way to recreate that feeling to stay up."

And the singer claims she was regularly offered drugs by promoters to entice her to keep returning to certain venues.

She adds, "Promoters gave me drugs and alcohol in restaurants or clubs. They wanted me to come back so I would be seen there. They were basically kissing my a**. I thought they were my friends. I thought I was having fun.

"Being a celebrity can be dangerous. Nobody says 'no'. That's why so many end up overdosing and dying. It could definitely have happened to me."
