Britney Spears sex tape for sale?

An infamous Britney Spears "sex tape" is reportedly being touted to the highest bidder, in the aftermath of her separation from Kevin Federline.

A leading porn mogul claims to have been approached about the tape last week, just days after Spears served divorce papers on Federline.

David Hans Schmidt, who is said to have bought and dispersed explicit footage on a number of entertainment figures, says he believes the footage will be leaked.

"Two days after Britney filed for divorce I was contacted by an individual who indicated that he had a digital video of Britney Spears and Kevin Federline having sex. This gentleman knew enough names and identified enough parties involved to indicate that the tape could exist," Schidmt told MSNBC.com.

Allegations about the Spears and Federline sex tape have been rife for some time. A U.S. judge recently dismissed a $10 million defamation lawsuit brought by the couple. Spears and Federline were seeking substantial libel damages from US Weekly, who suggested that the couple had made the video in an article last year.
