said last month that her past struggle with addiction would shock fans and now the singer shared the extent of the issue in an interview with Access Hollywood. Speaking from the set of "" on Monday, December 9, Demi said, "I'm very, very good at manipulating people and that was something that I did in my disease, I would manipulate everyone around me. There were times I would just continue to lie, so that everything looked OK on the outside."
"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," she continued. "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."
