Mischa Barton appears to have put her failed romance with rocker Taylor Locke behind her - after she was spotted leaving a London nightclub with actor Josh Hartnett.

The former The O.C. star hooked up with Hartnett and a male friend of his at the trendy Bungalow 8 club in the British capital during a party held in celebration of London Fashion Week. Barton was seen chatting to Hartnett at the nightspot, before she and a group of pals accompanied him to his hotel in nearby Soho, according to Britain's Daily Mail newspaper.

However, the Pearl Harbor actor, who is in London preparing to star in a West End production of Rain Man, apparently seemed unimpressed with Barton and she left the hotel just an hour later.

A source tells the publication, "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 the two guys were drinking champagne and vodka cocktails. Mischa had a lot to contend with, but didn't give up."
