Demi Lovato has never been shy to talk about her stint in rehab, but now she's opening up about exactly how she landed there in the first place. Speaking with Nylon magazine, the publication's latest cover confesses she refused to listen to her parents' advice and allowed her partying ways to get out of hand, saying "My parents tried to control me, but I’d be like, ‘Oh really, I’m grounded? Well, I pay the bills. They did the best they could. And I think that’s why a lot of young stars struggle when they’re making money or providing for their family."
