Paris Hilton's New Sex Tape Scandal?

Paris Hilton could be facing another sex tape scandal, according to a new book.

Mark Ebner - author of The Six Degrees of Paris Hilton - claims that the heiress is “seen in a state of arousal in a New York taxi" in a porno-esque home movie.

Mark’s book is about Darnell Reilly - a man who can boast of holding Girls Gone Wild founder Joe Francis hostage at gunpoint, partying with Mickey Rourke and boxing with Paris' original sex tape partner, Rick Salomon.

Darnell claims to have retrieved the footage from two "Russian kids" who broke into Paris' home to steal the tapes.
