KEY POINTS:
Pearl Harbor actor Josh Hartnett - who is currently starring in a London theatre production of Rain Man - was caught having sex in a hotel library by CCTV cameras.
The 30 Days of Night actor - who is currently starring in a London theatre 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.
A source told Britain's Daily Mirror newspaper: "Josh and the girl were getting pretty hot and heavy.
"Their every spit and cough was recorded and cringing hotel workers saw all of Josh's X-rated moves.
"No one quite knew where to look and there was a very awkward silence.
"Josh didn't seem bothered that the library wasn't locked and anyone could just burst in. He just kind of went for it."
After the romp, the 30-year-old star was "asked to take his personal business elsewhere" in the future by hotel workers.
The source added: "He has been very well behaved since."
