She might not have that Daisy Duke bod anymore, but Jessica Simpson still likes the way she looks these days.

"I got curves!" The Price of Beauty star, 29, tells E! News. "I can't get rid of them. There ain't no getting rid of them. At this point, I just celebrate them. I'm a healthy girl. I work out. I box. I try to eat right. I still like my corn dogs, my burgers and my onion rings. I can't help it. Just as long as I feel good about myself and if I feel healthy, I feel beautiful."

Last year, when she was slammed for her fuller figure, she says she felt "stripped of everything."

These days, the 5' 3½" singer - who fluctuates between a size 4 and 6 - doesn't care what people say. "I don't care how harsh the criticism is, you're not going to take me down," she says. "I'm going to get back up and fight. I'm not going to let anybody's opinions destroy me."

When does she feel most beautiful?

"When I am in my bathtub, listening to Sade," she says. "I also feel beautiful when I laugh and when I'm with my friends and I just have a T-shirt and booty shorts on ... with my heels on, of course."
