Hayden Panettiere Wants You to Look at Her Panties

“Heroes” star Hayden Panettiere surprised Ellen DeGeneres and her audience with a flash of some ill-fitting panties on Thursday’s broadcast.

“I’ll get you a smaller size,” the host responded after the 18-year-old actress hiked up her dress to show some boxer-like ‘roos that were apparently a gift from DeGeneres. “My friends dared me to do it backstage, and I said ‘Why not? … my dress is short enough.’”
