In an interview with Shape Magazine February 2009, 23-year-old High School Musical star Ashley Tisdale serves up her secrets for maintaining a slender figure.

“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.”

Ashley on Her Personal Trainer Christopher Hebert (with whom she’s been working with for about eight months): “He’s cute, which makes it fun, and he never lets our exercise session get boring.”

Ashley on Her Family’s History of Diabetes: “After I found out my grandfather has it and my mom is borderline, I knew I had to get serious about my diet too.”
