Their reps may deny it, but it sure looks as if "Heroes" costars Hayden Panettiere and Milo Ventimiglia are a hot couple.

Are they rehearsing for "Dancing With the Stars"? Are they just friends with dirty-dancing privileges? Or is this a serious romance? All in favor of the latter, say aye!

After watching the video, it’s clear that Hayden is the better dancer. And where were Milo’s hands, anyway?
