According to a soon to be released book, Paris Hilton is featured in another sex tape.

In Six Degrees of Paris Hilton: Inside the Sex Tapes, Scandals, and Shakedowns of the New Hollywood, written by Mark Ebner, it is alleged that the celebrity heiress shot footage of herself “in a state of arousal in a New York taxi.”

Ebner’s book tells the story of a man named Darnell Riley, the man who held Girls Gone Wild creator Joe Francis hostage with a gun and attempted to blackmail him, and is also known as a one time party pal of Mickey Rourke. Ebner had also boxed with Rick Solomon, who is most known as the ex-boyfriend of Paris Hilton and the costar of the One Night In Paris sex tape.

Riley makes the claim that he purchased 14 hours of video of Hilton from two “Russian kids” who had stolen the tape when they broke into Hilton’s residence.

Along with the alleged footage of Hilton being raunchy in the taxi, Riley says there is also footage of Paris at her grandmother’s funeral.

“She is sitting in the church shooting video of herself. She is paying no attention to the eulogy,” says Riley

Riley is currently serving a prison sentence for the blackmail attempt on Francis.

Six Degrees of Paris Hilton is slated for a February release.
