Celebrity Gossip – Beyonce Knowles, the singer/actress, has to watch what she eats and maintain a strict exercise regime to keep her bootylicious body in check. “I’m not one of those people who doesn’t have to work at it,” Beyonce tells Self magazine in its June issue.

“I can’t eat what I want, and I can’t not go to the gym.”

“I’m trying to do as much cardio as I can, so if I have a really long day of dancing [in rehearsals], then I’ll run maybe three miles,” the Obsessed star told the magazine a few days before her I Am… tour kicked off.

“If not, then I’ll run 6,” she continues. “I’ll put on a song that I really like and do [biceps curls with] 5-pound weights [for] the whole song and just try to burn out.”

But Bey, 27, doesn’t want it to look like she’s been hitting the gym.

“To me, sexier when it doesn’t look like you go to the gym. If you look like you’ve been spending a lot of time in the gym, then it just looks like you spend a lot of time in the gym,” she says.

“So I never want to get to that point where it’s not natural,” she goes on. “I think it’s important to feel like a woman, as well as look like a woman.”
