Hayden Panettiere HaydenStephenOver.jpgThis is what happens when you get too famous for your significant other! Us Weekly reports that Heroes star Hayden Panettiere has split up with her boyfriend Stephen Colletti (of Laguna Beach fame). When asked, "Where's Stephen?" at the VMAs this past weekend, Hayden replied with: "I don't know. In California?"

Burn! Hayden's so over that washed-up loser. But who is she moving on to next - perhaps one of her Heroes?
