Everybody’s favorite ‘Maybe Couple,’ Milo Ventimiglia and his barely legal rumored love Hayden Panettiere, have reportedly come out as a couple-at least to their Heroes castmates.

A spywitness tells In Touch Weekly, Hayden and Milo joined their co-stars and producers for dinner at the Water Grill in Downtown Los Angeles on December 15th, where thirty year old actor proposed a toast to his “girlfriend.”

“He called her his girlfriend and said that he loved,” the spy spills.

“And they sat next to each other holding hands…They snuck out very quietly so they could avoid paparazzi.”
