Perhaps one of the most embarrassing things to happen to a celebrity is the unwanted release of a sex tape. Plenty of stars have fallen victim to the release of titillating tapes revealing intimate aspects of their sex lives for all the world to see. Sometimes the tapes lead to prompt legal action, but in some cases, the amateur sex films actually do wonders to boost sagging careers.

First up is possibly the most famous sex tape of all time -- the one of actress Pamela Anderson and her former husband, rocker Tommy Lee. The video was shot during the couple's honeymoon after a quickie wedding and the couple alleges the footage was stolen from their Malibu home.
