is aware that many young Hollywood stars get tripped up by pitfalls of fame – but says she's not one of them.
"I think that people look at me as just another one of those girls who's going to screw up, like 'She's going to get into drugs, and she's going to get into the parties,' " the 18-year-old Heroes
star tells Cosmopolitan magazine
in its April issue. "I have the occasional glass of champagne when I'm celebrating something, but generally, I don't drink. I'm a pizza-and-a-movie girl."
Similarly, Panettiere says she does not worry about Hollywood's standards of beauty when it goes to her figure. "I don't have a model's body. But I'm not one of those crazy girls who thinks that they're fat," she says. "I'm okay with what I have. I can rock this body, you know?"
But there is one area of her life in which the pressures of being an actress can be tough: romance.
"I need somebody who is very secure," says Panettiere, who is mum about her relationship with her Heroes
costar, Milo Ventimiglia. "In this business, I'm constantly standing next to gorgeous people. My job is to make out with [attractive] men. Like, hello
, who wouldn’t be completely threatened by that? But at the end of the day, you have to realize that it's just a job."
