Jewel rocks a bikini on the cover of the July issue of Shape (via Just Jared) -- and looks really, really good. In the accompanying cover story, the singer-songwriter talks about her fluctuating weight, her new diet and how it felt being called the "chubby Renee Zellweger."

On being called the "chubby Renee Zellweger" when she first became famous:
"My feelings were so hurt by that story, I ended up binging on an entire cake. Afterward, I actually tried to throw it all up, but thankfully I couldn't do it. It made me think, 'I can't go down this road.' I had seen so many performers develop eating disorders or try to control their weight with drugs, and I decided I would do no harm to my body."

On why she skips cosmetic dentistry or plastic surgery:
"I had to remind myself that standards of beauty are very fickle. One minute J. Lo's body is considered beautiful, and the next everyone wants to look like Kate Moss. I'm all for people wanting to feel more confident, but altering your body to fit a current trend is serious stuff."
