The National Enquirer is reporting that Adnan Ghalib is shopping around an alleged sex tape that he made with Britney Spears when they were in Rosarito, Mexico.

A source said, “Word is that the video starts with Britney undressing. She was wearing some cheap clothes that she bought down there in Rosarito. The sex wasn’t particularly kinky but Britney wears a pink wig throughout. At one point in the tape Adnan asks the singer to remove the pink bob but she refused. “Adnan tells her to take it off at one point and she says coyly, ‘Take what off? There’s nothing left to take off.’”

An insider claims that if this tape is for real, it could possibly be the highest selling-sex tape of all time, out selling Paris Hilton’s even.
