"Heroes" Hayden Panattiere & Milo Ventimiglia Split

Stars of Heroes, Milo Ventimiglia and Hayden Panettiere, have broken up.

Different lifestyles was the reason why they broke up. "They lead different lifestyles. He's 31, she's 19. She still has growing up to do and he's very low-key," said a source close to the couple. "The relationship never seemed like it had legs."

The two have been together for about two years. They spent part of 2007 hiding their relationship. Ventimiglia and Panettiere may have broken up but they are still friendly to each other.

I never thought that they would last very long with such an age difference.
