Hayden Panettiere is this year's GQ "obsession," with a sexy spread in the Man of the Year issue. That must be why she was posing with every hunk at the party. Except her "Heroes" costar Milo Ventimiglia, who looked a little displeased with the situation. Hayden even latched on to Drew Barrymore's rumored squeeze, Justin Long, who looks like he's thinking, 'Please, God. Please don't let Drew see this picture.'
