A grunged-out Demi Lovato covers the January issue of Nylon magazine and opens up about rehab, recovery and keeping things honest.

With the release of her fourth album, a New York Times best-selling book and nail art collaboration — and who could forget her second season as an X-Factor judge— Demi’s career is clearly riding high.

But as the (only!) 21-year-old will readily admit, the road to her most successful year yet has been a rocky one.

In 2010, the former Disney star landed herself in rehab after growing up a little too fast. “My parents tried to control me, but I’d be like, “Oh really, I’m grounded? Well, I pay the bills,’ “; she says.

“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. My mentality was “Work hard, play hard. 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.”;

The X-Factor judge is working hard to shed her troubled past and she’s been doing so by moving beyond singing and acting.

“I look at my life and think, “There’s not enough time.’ I co-directed my last two videos, and I have this dream of being behind the camera and one day directing my own movie. I want to host my own show and be a younger Oprah. I want to write songs for other artists. I want to be an author. I want my own makeup line, and my own skincare line. I want to do a lot more philanthropy work, and for a while there I thought I wanted to go to law school.”;

But no matter what she tries to tackle next, Demi will always value the relationship with her fans— a relationship that she says is an open and honest one. “When I went into rehab, I deleted my Twitter…I didn’t want to force anything. My parents came to visit, and I asked if people knew yet, and they said, “Yeah, it’s everywhere.’ And they were like, “How do you want to handle this? We can say it’s a personal time and we don’t have to tell them what you’re in here for, or we can just be 100 percent honest and show them that you can get through it and other people can get through it, too.'”;

“I have probably the best relationship between any artist and their fans, because I have no secrets,”; she added.

Demi will be celebrating her successful year and ringing in a new one with ET Canada at the 5th annual “New Year’s Eve At Niagara Falls” bash on December 31. She’ll be joining Serena Ryder and Sam Roberts Band for the two and a half hour event kicking off at 10pm on Global TV.
