Heath Ledger Enjoying Open Season

Is Heath Ledger already on the prowl? It's been just days since the actor's split with Michelle Williams was made public and already we've seen him hit the town for two marathon nights. The first was on Sunday, when he attended a Dazed & Confused magazine dinner at Bowery Hotel with five friends and ended up getting squired around the city by Amy Sacco, who took him to Narciso Rodriguez's tenth-anniversary party on the roof of the Gramercy Park Hotel, then to the Rose Bar downstairs, and finally to the Box, where he spent quality time in a banquette chatting up a chicly dressed blonde who looked like a taller Sienna Miller.

Then last night he got mouths flapping by showing up at the Cinema Society screening party for Eastern Promises at the Soho Grand penthouse with Helena Christensen. (They'd come from the Calvin Klein post-show dinner at Gramercy Park Hotel and have known each other for years, she assured us.) There he flitted around the roof deck from babe to babe, making it pretty clear that he and Christensen hadn't shown up to the party as anything but friends. At least he appears to be approaching his new singledom with an open mind to type. The model we saw him chatting up had long wavy hair that reached halfway down her back. Though she was wearing a hat that looked eerily similar to the one Ledger had donned on Sunday night. —Jada Yuan
