Kelly Carlson may play plastic surgery-obsessed porn star Kimber on FX's drama Nip/Tuck, but offscreen, the actress doesn't strive for physical perfection. "I don't let that control me.

I just had half a cheeseburger!" the blond beauty told In Touch at the Style Magazine winter issue launch party at The Palazzo Resort Hotel Casino in Las Vegas on February 27. Instead, Kelly, who dates former NHL player Tie Domi, just focuses on fitness. "I treat my body like a machine," she added. "I try to keep it as healthy as possible. You just feel better!"
