How appropriate is it that Hayden Panettiere's character on Heroes happens to be a cheerleader? When we spotted the show's cast gathering for an appearance in Paris to promote the first season's release on DVD, she couldn't have drawn more cheers from the throngs of shrieking, chanting fans if she'd had a pair of pom-poms readily at hand! Still, Hayden handled it like a pro, smiling and waving back at the fans (and sincerely thanking a few lucky diehards who were able to slip her a late birthday present). Gooooo Hayden!

(One person who might have kept quiet, however, is Hayden's recalcitrant boyfriend Stephen Colletti - after all, the sight of your girl all over a guy like Milo Ventimiglia sounds like a great way to dampen your spirit!)
