Make no mistake: Ashley Tisdale is a Disney teen no more. To prove that point, the former High School Musical star, 27, poses in next to nothing in the May issue of Maxim: Going topless on the cover (barely covered up by a black leather jacket and wearing frilly panties) and, inside, flashing a jaw-dropping amount of sideboob in a low-cut white shirt (and no bottoms).

Inside, as Tisdale promotes Scary Movie 5, she talks about her taste in men. "There's definitely a thing where I like the dark, mysterious bad boy," says the blonde, currently dating Christopher French. Another type she loves? "Surfer, blond frat guys," says Tisdale, whose exes include another musician, Jared Murillo, and director Scott Speer.

"I'm definitely old-school when it comes to dating," she shared. "I'm not into the 'game' so much." Her advice to potential suitors: "If I like you, I'll confront you and be open about it. Then I expect you to come after me."

Tisdale, who's still close with HSM pal Vanessa Hudgens and other young Hollywood stars, also shares her own romantic wisdom with friends. "I give dating advice on a regular basis. It's not that I'm any expert, but it's always nice to share that with your friends."
