Best: Kristen Bell

Kristen's joining the Heroes cast but she won't spill what her super hero power is. But she did let in on a little inside scoop. "I have an awesome super power and I think it's the best one!" she said. Well, we think Kristen's got the best style from the Heroes cast. (You gotta see what Hayden was wearing!) We heart this former Veronica Mars star's draped periwinkle gown. It's very Greek Goddess meets red carpet Fashionista. Love it!
