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.
