Demi Lovato reveals she "couldn't go 30 minutes without cocaine"
American X Factor judge Demi Lovato has revealed the extent of her drug and alcohol addictions, admitting she turned her life around for her younger sister.
In a particularly candid interview this week, the singer admitted that at the height of her addiction, she couldn't go longer than 30 minutes to an hour without cocaine and even 'smuggled' drugs on board flights in order to get her fix.
Lovato's behaviour had become so out-of-control that her mother threatened to move away from the Hollywood scene, taking her younger sister, actress Madison de la Garza, out of her life.
The star was not allowed to see her now 11-year-old sister, who played Juanita Solis in Desperate Housewives, as she spiralled out of control.
She recalled how during a dark period in her life she would even smuggle drugs onto airplanes.
‘‘I couldn't go 30 minutes to an hour without cocaine and I would bring it on airplanes,’’ she said.
‘‘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 into the bathroom and I'd do it,’’ she added.
In an interview with Access Hollywood, the singer opened up about her past alcohol and drug abuse.
The former Disney actress admitted she lied to those around her to disguise her secret substance abuse.
