If your famous leave the cameras out of the bedroom!

Britney Spears' estranged husband Kevin Federline is reportedly threatening to sell a homemade sex video of the pair unless he receives 16 million and custody of their children. Kevin has allegedly vowed to sell the explicit four-hour tape to a company who want to post it on the internet unless Britney agrees to his demands. A source told Britain's News of the World newspaper: "It makes Paris Hilton's homemade video look like a Disney cartoon. This footage is dynamite and Kevin knows it. "He has told Britney she could comply with his demands otherwise the whole world will see her having sex."

A film company in Arizona has allegedly offered Kevin £26 million to allow the video to be viewed online. The 'Toxic' singer is reportedly terrified the X-rated video will destroy her career and see her lose her sons Sean Preston, one and two-month-old Jayden James. Kevin, 28, has told friends the tape shows footage of Britney performing a number of explicit sexual acts. The tape was allegedly made in the first two weeks of their relationship in Los Angeles' Beverly Hills Hotel. A source said: "They were in the honeymoon stages of their relationship and did nothing all day but have sex and play chess. Britney didn't think twice about making the video, she believed their love would last."

Britney has reportedly contacted her lawyers to see if she can stop Kevin selling the video, but because it's his tape he owns the copyright. The 24-year-old is said to have filed for divorce after finding Kevin in a New York hotel room with another woman. Kevin is entitled to 2 million and half of the money from the sale of their 7 million Santa Barbara home according to the couple's prenuptial agreement.
