Has Heath already moved on?

Heath Ledger isn't letting any grass grow under his feet. Just a week after announcing his split from Michelle Williams, Ledger has reportedly been squiring ex-model Helena Christensen all over town. Tuesday night, the two were at Wakiya in NYC "making out throughout the dinner," said a spy. Acting like a good boyfriend, Ledger allegedly even "held her bag for her as she did interviews." The two then went to the afterparty for the movie Eastern Promises at the SoHo Grand, and ended up at the Spotted Pig.
