Not content to have a lifestyle and career most people would kill for, she also had the pleasure of hooking up with gorgeous actor Josh Hartnett after they bumped into one another at trendy club Bungalow 8 last night. Mischa, who recently split from musician boyfriend Taylor Locke is clearly keen to put the past behind her.

The OC star spent a good hour writhing in front of Josh at the bar last night, and must have made an impression as they both headed back to his hotel at the end of the night. Not to suggest that anything happened between the extremely good-looking and single pair - and Mischa did trundle back to her own hotel an hour later. The actress, 22, looked desperate to impress Josh at the Temperley afterparty at Bungalow 8 when she arrived at 11pm.

Hartnett, whose screen credits include Pearl Harbor, is in London to play Charlie Babbitt in the Apollo Theatre's production of Rain Man. Josh, 30, was sitting with Kings Of Leon drummer Nathan Followill and seemed more interested in his conversation than the strutting beauty. A source said: '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.'
