Ashley Tisdale graces the January 2009 cover of Shape magazine.

Inside the issue, the High School Musical star dishes on her waist size, guilty pleasures and more...

On body size: “I was always super thin — too skinny, actually. I felt like someone could break me in half.”
On her guilty pleasure foods: “I love carbs. Bread, corn bread, french fries—all that stuff.”
On eating well: “I’ve found I’m definitely eating better since I started working out more rigorously. It kind of happened naturally. I don’t really crave junk food that often now.”

Is Ashley Tisdale in Shape? In a word: YES!
