Kelly Clarkson slams weight critics

(People.com) -- Over the past few months, Kelly Clarkson's weight has been a hot topic for critical bloggers. But the outspoken singer -- who has said "Of course celebrities have cellulite!" -- doesn't let the body bullies get her down.

"When people talk about my weight, I'm like, 'You seem to have a problem with it; I don't. I'm fine!'," Clarkson, 27, told the September issue of Self.

She also noted, "My happy weight changes. Sometimes I eat more; sometimes I play more."

These days, the play part means golf ("I love it!") as well as Crossfit workouts. "It's like bootcamp!" she said of the regimen that includes sit-ups, squats and running. "You never work out more than 35 minutes, but it's so intense ... It makes me feel like G.I. Jane. It's very empowering. I feel like I can whup ass!"

Indeed, Clarkson's motivation for exercising isn't to lose weight.

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

The Texas native admitted she still eats chicken-fried steak, but also has days when she prefers salads.

"I love healthy stuff and junk an equal amount," she told the magazine. "Whatever I'm craving, I go for it."

Her secret to losing weight, in fact, is to not go on a diet: "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!"
