Federline to sell Britney sex tape?

Kevin Federline is threatening to make public a honeymoon sex video that he made with Britney Spears, the News of the World reports today.

The newspaper claims that the aspiring rapper is in talks with a film company to sell the tape and will go ahead with the transaction unless Spears agrees to his divorce demands.

A source explained: "Britney didn't think twice about making the video at the time. She mistakenly believed that their love would last. They adored filming each other. They lived their lives in front of the cameras - even making a short-lived reality TV show of their exploits.

"Sex was no different to them, it seems. Now this video could prove very costly to her. Millions of people will be prepared to pay to watch. Kevin has told Britney she should comply with his demands otherwise the whole world will see her having sex, which will be devastating."
