Lovato: It was hard to hear 'no'
Demi Lovato has revealed that being the family breadwinner as a child star contributed to her downward spiral.
The X Factor USA judge - who has suffered from bulimia, self-harming and depression and ended up in rehab in 2010 - started out on children's show Barney And Friends as a 10-year-old, and went on to have both acting and singing careers.
She admitted to Nylon magazine that paying the bills made her want to make her own rules when she was growing up.
Demi, 21, said: "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."
Demi, whose dad died earlier this year, went on: "It was hard to listen to the word 'no'. I wanted to make my own rules. I thought that if I was adult enough to get there, then I could party like an adult. And obviously, I couldn't."
Demi has since left her troubles behind her and earlier this year told how her social life reflects the changes she has made.
The Neon Lights singer told Teen Vogue: "It may seem boring to other people, but my whole life I've lived at a really intense level - whether it's fame or this or that.
"I've always worked really hard. Now I've gotten to the place where I'm healthy, happy. And my family is happy and healthy. When I do have free time, I love just sitting here and inviting people over and watching movies, or going to the movies. It's a big night for me if I go bowling."
