Milo Ventimiglia, Hayden Panettiere Do Lunch (and That’s Probably All)

Heroes hotties Hayden Panettiere and Milo Ventimiglia grabbed lunch together at a cafe near her West Hollywood apartment on Wednesday.

Co-stars eating together? Hmm. Should Stephen Colletti be worried?

We doubt it. But it’s neat to see that Heroes like Hayden Panettiere and Milo Ventimiglia apparently hang out off the set as well!
