Josh Hartnett caught having sex in library

Josh Hartnett thoroughly gets off being in front of the camera, whether on film ... or closed circuit television.

The hunky film star, who turned thirty in July, slipped into the Soho Hotel's library while in London last weekend and proceeded to shag a yet to be named female companion. And little did Hartnett know but hotel personnel were watching every seedy minute on CCTV. Pass the popcorn, please!

As one witness pointed out, "Unfortunately the hotel has security cameras all over the place - the library included. ... This means their every spit and cough was recorded, and cringing hotel workers saw all of Josh's X-rated moves."

Cringing? Was is really that bad?

"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."

It wasn't until after the deed was done that a hotel manager had a quiet word with Josh. The Soho Hotel staff are discreet, even if some of their guests aren't. Which is why their is no "Josh Hartnett Sex Tape"  circulating the Web right now. Believe us, we've checked.

If this isn't reason to spend more time at the library, we don't know what is.
