Milo Ventimiglia and Hayden Panettiere
Onset romancers Hayden Panettiere and Milo Ventimiglia have more than just their leading roles on Heroes in common. Both stars are staunch vegetarians and Panettiere recently risked arrest to protest the killing of dolphins in Japan. As a result, Ventimiglia watched the petite actress get honored by the Humane Society with their Gretchen Wyler Award for activism.
