But can't you just picture Heroes star Hayden Panettiere turning into one of those types any day now? The Hollywood starlet has been making the club rounds... we can't wait for her to start showing up late to the set of her show and all the cast members hating on her! (Not that we want that, of course.) Here's Hayden getting some coffee (mmm, caffeine) in La La Land. But why the oversize shirt? If you got it, flaunt it!
