What Is Vanessa Minnillo So Embarrassed About?

Vanessa Minnillo is up there with Hollywood’s hottest, but it seems the starlet is less than satisfied with at least one stubborn body part.

"I always have problems with my abs, especially when I see these women who have beautiful, sculpted abs," she groaned to Tarts at last week’s launch party for Reebok’s new Easytone sneakers. "My parents are like ‘you're a woman, you're supposed to have babies, you're supposed to have a womb,’ but I cannot tone them for the life of me, so that's my trouble spot."

But the newly on-the-market starlet isn’t shedding any tears over ex-fiance Nick Lachey, and is busy getting bikini-buff for the next beau that comes along.

"I just got back on this kick because it is summer time and we all have to squeeze into our bikinis. I just started working out threedays a week and I love it," Minnillo added. "I love the feeling. It's good for your serotonin level, my clothes fit me again now, its beneficial on so many levels, both inside and out."
