Heath (hits the) Bars

Aussie-born actor Heath Ledger, recently separated from his Brokeback Mountain co-star (No, not Jake Gyllenhaal) Michelle Williams, has been on the prowl. After moving out of the couple's shared Brooklyn digs, Ledger has been seen at quite a few  Manhattan night spots putting the make on the ladies.  Over the past few months, he's been romantically linked to the likes of Helena Christensen and Kate Hudson.  Recent rumors have the Casanova (now that was a bad movie) star trying to bed--but without much success--Heather Graham  and  also Gemma Ward (we assume not at the same time).   Let's hope all this catting around and gin-mill carousing will not harm his career--as it has his fellow Down Under thespian, Mel Gibson (they were in The Patriot together).   Of course, if he's still getting work after the Brother's Grimm, what's really the worry.
