Hayden Panettiere Dating Jesse McCartney

Looks like Hayden Panettiere and Milo Ventimiglia are over because she was all over Jesse McCartney last night. Hayden Panettiere and Jesse McCartney were spotted at Crown Bar making out like teenagers, which is, uh, exactly what they are.

Hayden Panettiere, 19, and Milo Ventimiglia, 31, called it quits a little while back and Hayden Panettiere wasted no time and went straight to Jesse McCartney, 21, to get back to her age bracket.

What do you think of this new couple? Will Hayden Panettiere and Jesse McCartney last? And how awkward will it be for Hayden and Milo to be on the set of Heroes?

Shirtless Celeb Of The Day - Milo Ventimiglia

Ever since Heroes began, I knew I wanted to see Milo Ventimiglia naked, preferably with me in the room at the time. Unfortunately, neither has happened so far, but I've got my fingers crossed and my legs open, waiting for it to happen soon. For now, I'm content to see him without his shirt, giving me that "come to me" look.
