Demi Lovato's very revealing MTV documentary "Stay Strong," reaches deep inside a dark place she's never opened up about before.
While the "X Factor" judge has been up front about her struggles with self harm and bulimia she has never opened up about the severity of her past drug addiction.
The singer and judge reveals during her documentary:
"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 said in the interview. "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."
