Kelly Rowland On The October 2013 Cover Of SHAPE Magazine

Kelly Rowland may not be performing as a member of Destiny's Child anymore, but the sultry singer is definitely still "bootylicious."

The "Dirty Laundry" singer, 32, covers the October issue of SHAPE magazine, bearing her incredibly toned bikini body.

Working closely with trainer Jeannette Jenkins, Rowland revealed she has an intense workout regimen which she does five or six times a week.

I use my core for everything," she told Us Magazine. "Absolutely everything. When I'm dancing on stage, when I'm walking around — I have to make sure that my core is strong, is tight. You use it for everything."

The "X Factor" judge also attributes her shapely figure to "clean eating."

"I never like to say diet," she said, in a recent interview with TheYBF.com. "I like to say eating clean … For me, it's green vegetables or fish. I don't feel like I'm heavy or weighed down or lethargic when I eat. Food should give you energy.

"All I need is a good workout and that's it. I take of myself, take care of my skin, and I watch what I'm eating."

But not all the time — Rowland also added that she likes to indulge in "cupcakes! Or anything with sugar or chocolate sauce."

Her motivation for staying in shape? Rowland said she likes to look good naked.

"I want to look good naked. ... Everybody wants to look good naked. That's the goal."
