Demi Lovato takes it off in the February issue of Allure and strips down emotionally, too.

Yes, she talks about self-image and her struggles with weight -- she even reveals having fixed the gap in her teeth at the request of Disney casting, which she now regrets. The singer-actress tells the mag, of haters who are sick of hearing her talk about her body issues:

    "I'll have people who are like, 'Stop talking about eating disorders. Like, we get it. You struggled. Now shut up. I started wearing sexier stuff, and I got some hate for that -- like, 'You've changed."

And about her new confidence and her new look:
    "I've never felt as confident in my skin as I do today. A year ago, on tour, almost every inch of my body was covered by clothing ... Once I started feeling better about myself, I felt better about showing more skin. It's also a statement, like, 'Hey, watch out. You're no longer getting the insecure Demi that you've been getting for the past couple of years. I mean business now."

Demi's on fire!
