Hayden Panettiere made a named for herself playing Claire Bennet, a popular high school cheerleader that saved the world on the NBC sci-fi series Heroes. But in real life, Hayden suffered through years of psychological “torture” at the hands of her classmates.

Hayden said she started to feel different than the rest of her classmates as early as grade school.

“I was tortured, emotionally tortured by these girls,” the star of the new I Love You, Beth Cooper reveals in the August issue of Details Magazine. “Every time I came back from filming, it would be me trying to find my way back into the clique. And they weren’t having it.”

She added, “I remember hearing in first grade, ‘Oh, why does she get to skip school?’ It wasn’t like I suddenly started feeling different. I always knew that I was. I never felt I missed out—in fact, it was like, ‘Oh, thank God I’m not that.’”

It’s one thing if you do it to me. I get frustrated, but I can handle it. But when it involves my family, my friends, forget it—I lose my… I learned the game. The more I react, the angrier I get, the more satisfaction they get. That’s exactly what they want.”
