Kelly Clarkson has a message for anyone that thinks she's overweight:

You're the one with the problem, not me!

This self-assured, admirable American Idol champion covers Self this month and goes off on her critics inside the magazine's pages.

Here are excerpts from her empowering interview:

On her critics: When people talk about my weight, I'm like, You seem to have a problem with it; I don't. I'm fine!.

On exercising: I do it totally for my psyche. I'm much better when those endorphins are going. It's a release. And I also love food, so there's a payoff!

On eating habits: I love healthy stuff and junk an equal amount. Whatever I'm craving, I go for it.

On being herself: For me, it's the times when I'm not paying attention that I end up losing weight. But I'm never trying to lose weight – or gain it. I'm just being!

We have three words for Kelly Clarkson: You. Go. Girl!
