Demi Lovato is a hair and style chameleon, but she always manages to look like herself -- she's never forcing anything. Aside from her multitude of looks, she also has multiple talents ... and multiple issues that eventually led to rehab. She opened up about everything to Nylon.

Lovato's main issue now? Her schedule! "I look at my life and think, 'There's not enough time,'" she said. "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." Phew!

As for her other issues, Lovato is as candid as ever. "When I went into rehab, I deleted my Twitter ... I didn't want to force anything," she admitted. "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.'" We all know which route she took!
