Mischa Barton spent Monday evening with Josh Hartnett.

'The O.C.' actress - who recently split from her musician boyfriend Taylor Locke - met up with the '30 Days of Night' actor at exclusive London nightclub Bungalow 8 and after chatting together the pair reportedly left for his hotel at the end of the night.

Mischa, 22, managed to get the 30-year-old actor's attention by dancing seductively in front of him as he sat talking to Kings of Leon drummer Nathan Followill, but he was initially unimpressed by her moves.

"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."

Nathan was reportedly unconvinced by Mischa's display, and was heard warning Josh off the actress. The source added to Britain's MailOnline website: "Nathan told him that he thought she talks too much."

However, Mischa and Josh eventually left the club together and traveled to Josh's room at the plush Soho Hotel at 1.30am.

Mischa emerged from the establishment one hour later and returned to her own hotel.
