Hayden Panettiere is spunky and pretty, but no match on the adorable factor with that amazing little French Bulldog on her shirt asking to be adopted. Awwww, I want him! She was spotted grabbing lunch with an older, male costar from Heroes, but not the one everyone would expect. Instead of her rumored paramour Milo, she was out with Greg Grunberg, who plays Matt Parkman on the show. Hayden is obviously the little sister to all her big male cast members on the show...you know, even though to one she may be something more.
