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.

Josh Hartnett was caught on CCTV having sex in a hotel library. The "30 Days of Night" actor - who is currently starring in a London theater production of "Rain Man" - was unaware he was being watched by hotel staff as he romped with a mystery woman.

Trying to be discreet, the star drew all the curtains in the wing of the Soho hotel, but failed to spot the surveillance cameras filming his every move.

The 29-year-old actor will play Charlie Babbitt, a selfish yuppie famously played by Tom Cruise in the 80s film version. Harnett will make his debut at the Apollo Theater on August 28.

Actress Eva Mendes reportedly may have checked herself into a rehab clinic in January to prepare herself for a new role where she plays a Spanish drug lord.
