"I don't think I'd ever do a topless role," the 27-year-old blond beauty told us at her Scary Movie 5 premiere this week.
"I'm very comfortable in my body," she said. "I'm definitely more of a comedian. I don't really take myself too seriously."
Tisdale shows lots of skin—and cleavage!—in her May Maxim cover, posing in only tiny panties and a cropped leather jacket.
"Maxim was fun and I was really excited," the former High School Musical star said. "It was shot at the beach in Malibu, and I'm, like, a beach type of person. I feel like it was cool."
Tisdale added, "I'll do drama and stuff but I don't think I'll ever go topless for something."
