A sex tape featuring actress Vivica A. Fox has reportedly been leaked.

The tape was recorded on a cell phone by one of Fox's companions, and was then emailed out to several of his friends.

A copy was also sent to Fox, who immediately turned it over to the police. We're not yet sure how many copies have been circulated, and they have yet to show up on the internet.

Fox is an American actress best known for films including Independence Day and Kill Bill. She was married to singer Chris Harvest in 1998, and they later divorced in 2002. In 2003 she began dating rapper 50 Cent.
