Demi Lovato believes promoters gave her free drugs in a bid to get her to return to their clubs and restaurants. The former Disney star claims people in Hollywood used to fall over themselves to give her illegal substances.

"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," she said.

The "Skyscraper" singer - who also suffered from bulimia - admits she used to use alcohol and drugs to drown out her misery. "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 to find a way to recreate that feeling, to stay 'up,'" she said when asked about rumors she used to take cocaine.
