Former Disney star Demi Lovato was so dependent on cocaine that she would "smuggle" it on to airplanes before she entered rehab.
"Something I've never talked about before, but with my drug use I could hide it to where I would sneak drugs. I couldn't go without 30 minutes to an hour without cocaine and I would bring it on airplanes," Lovato said in an interview with Access Hollywood.
"I would smuggle it basically and just wait until everyone in first class would go to sleep and I would do it right there. I'd sneak to the bathroom and I'd do it. That's how difficult it got and that was even with somebody [with me], I had a sober companion, somebody who was watching me 24/7 and living with me [and] I was able to hide it from them as well."
Lovato, 21, is promoting her forthcoming memoir, out later this month, called Staying Strong: 365 Days a Year.
It wasn't drug use that finally made her decide to change her life, however. It was alcohol. She told Access Hollywood of going to an airport in the morning with a Sprite bottle filled with vodka.
"I think at 19-years-old, I had a moment where I was like, 'Oh my God … that is alcoholic behaviour. [It's] no longer, I'm young and rebellious and out having fun. It was, wow, I'm one of those people … I gotta get my s*** together," she said.
The X Factor judge also said she developed an eating disorder at eight or nine years old.
Lovato is among a long list of former Disney stars to run in to personal or legal troubles.
The mouse factory has produced some celebrities who have avoided the pitfalls of their peers, including Ryan Gosling and Miley Cyrus (okay, she's controversial, but she's not drug addict controversial). Many more, however, have wound up in the celebrity press for all the wrong reasons.
