As one of the hottest stars in America right now, Tina Fey has every right to feel good about herself, but the petite comedian hasn't always been so confident. Fey, currently gracing the cover of Vanity Fair Magazine, spoke out about her body image, revealing that she started dieting after seeing herself on TV as a SNL extra seven years ago. "I was starting to look unhealthy. I looked like a behemoth, a little bit," she says.

How did she slim down? Here's what Fey told Woman's Health: "When I was 29 - I am 36 now - I lost about 35 pounds. I did it through Weight Watchers. That's when I learned how to eat properly for the first time. Before, I used to be one of those people who wouldn't eat anything all day, then eat a piece of cake at 4 p.m., McDonald's at 10 p.m., and then go to bed."

Whatever she's doing is working -- she looks great! What do you think?
