Milo Ventimiglia and Hayden Panettiere have been denying rumors about them being together for a long time ... they're only co-stars and he's looking out for her and they're only friends ... bla bla!
But, what happens when they're spotted holding hands? Are they lying? Or is it still a rumor?
Well, the Heroes stars were together at a week-end screening of the movie "Atonement" somewhere in L.A. and they were seen holding hands.

Have the two decided to take their relationship to the public level?
You decided for yourself until something official comes out!
