Dec. 11 (UPI) -- Former party girl Demi Lovato spoke out about her drug use during a candid interview with Access Hollywood's Kit Hoover Monday.
While the 21-year-old X Factor judge has always been outspoken about her struggles with substance abuse, eating disorders and self harming, Lovato recently said she's conflicted about how much to reveal about her old habits.
“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 told Hoover.
“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.”
The "Heart Attack" singer went on to say she hit rock bottom when she was 19-years-old on a day she was drinking from a "Sprite bottle just filled with vodka and it was just nine in the morning."
“When I hit that moment I was like, it’s no longer fun when you’re doing it alone. I’ve really never talked about this stuff before… I don’t know if I should be sharing this," she said.
Lovato explained that she went from thinking "[It’s] no longer, I’m young and rebellious and out having fun," but instead "it was, wow, I’m one of those people…I gotta get my [expletive] together.”
The singer also spoke of her eating disorder, which began before her teen years.
"I went to just completely starving myself and that turned into throwing up and starving myself and it was just this crazy battle going on inside of me,” she said. “It got really difficult [and] I would throw up and it would just be blood and it was something that I realized if I don’t stop this, I am going to die.”
Lovato's mother, Dianna, who was also at the interview, said she ignored her daughter's problem for a long time because she wanted to believe her when she said everything was fine.
“I suspected [she was using drugs]. It’s like any other parent, when you see things, when you see signs you don’t want to believe that’s what actually going on. So when they’re telling you that’s not what is going on… you want too badly to believe them and I think for a long time I was in denial,” she said.
