Demi Lovato recently confessed she had to conquer a drugs habit

American X Factor judge Demi spoke out about her addiction for the first time this week, revealing to Access Hollywood: "I couldn't go without 30 minutes to an hour without cocaine and I would bring it on airplanes. 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."

Fellow former Disney star Selena tweeted a picture of her and Demi together cuddled up in front of some Christmas lights in hats and scarves.
Demi replied: "I looooooooooovvvvvveeee you."
According to Entertainment Wise, Selena joined Demi as she visited a rehab centre to give an inspirational speech about her own recovery.
Demi entered rehab in 2010, and at the time it was reported she was battling bulimia and bipolar disorder. She has since opened up about her personal demons but had not admitted taking drugs until this week.
She tweeted: "I've been through hell and back, but my story isn't over yet... I can't wait to talk about the people who have never taken ANY credit for being a huge part of saving my life, and why I'm alive today..."
