“Taylor Locke, who?”

Mischa Barton knows how to get over a broken heart – rebound sex!

Last night while partying at club, Bungalow 8, Mischa, who just split up with boyfriend Taylor Locke, was on the prowl.

And her prey was Josh Hartnett.  And who can blame her??

Apparently Mischa tried desperately to get Josh’s attention by “writhing in front of him for a good hour.”

A source tells the Daily Mail,

“Josh looked pretty bored and was totally ignoring Mischa. She persisted though, and kept getting closer and closer to their table while dancing provocatively. Lots of girls were trying to get near their table, where [Josh & friend] were drinking champagne and vodka cocktails. Mischa had a lot to contend with, but didn’t give up.”

And her persistence paid off. She went back to his place afterwards where she stayed for about an hour. Freaky sex? Simply smokin’ a spliff?

Who knows, but one things for certain – what Mischa wants, Mischa gets!
