"Heroes" hottie Hayden Panettiere isn't only not dating co-star Milo Ventimiglia, she doesn't even remember who he is!
TMZ caught Hayden and her sexy mom leaving Orso yesterday, where we asked the droll cheerleader if she was going to spend the holidays with Peter Petrelli. Her initial response: "Who?" Burn!
FYI -- she's also not getting back together with "Laguna Beach" ex-boyfriend Stephen Colletti, so now's your chance, if you dream you have one.
Hayden Panettiere -- Milo Who?
