LINDSAY AND HEATH...

Chatter from Australia is that Lindsay Lohan hooked up with Heath Ledger in New York, prompting her to dump that no-name dude she met in rehab.

Lindz and Ledger reportedly met at NYC's Beatrice Inn over the Thanksgiving holiday.

"Lindsay and Heath hit it off straight away," reports NW magazine. "When she left the club she started texting him straight away and they hooked up a few times while she was still in New York. They were meeting late at night for sex. It was purely physical."
