's weight has been a hot topic for critical bloggers. But the outspoken singer – who has said

"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, tells the September issue of Self
She also notes, "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 says 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 explains. "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 admits she still eats chicken-fried steak, but also has days when she prefers salads. "I love healthy stuff and junk an equal amount," she tells 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!"
