David's Sex Vid Blunder

David Arquette David Arquette was left a lil' red-faced recently...

After a hospital patient caught him watching what looked like a sex tape.

But believe it or not, there is an innocent explanation.

Courteney Cox's fella was actually working at the time of the incident.

He was editing a scene from his wife's scandalous TV drama Dirt, from an episode he directed.

But when Courteney's mother was taken to a hospital in Ohio for open-heart surgery, David came along too - with his work in tow.

"We were in the hospitality suite," Courteney explained to Wenn.Courteney Cox

"And David’s watching the computer of his cut and giving notes from Cleveland. There was this part he was watching, where there was like a home sex video.

"He was really into it… and this woman walks by, looks over his shoulder and says: 'What are you doing?'

"She thought he was just sitting in the hospitality suite enjoying some sex show."

Oops.
