This one is said to be set in a NYC Taxi Cab.

The hotel heiress has dabbled in both singing and acting, but its her amateur sex tapes that he garnered her the most most fame and sales. First there was the infamous "One Night in Paris" video, and then came the unnamed film shot in night vision. Now there is said to be a third Hilton sex tape floating around, this one set in a NYC taxi.

In Marc Ebner's new book, "Six Degrees of Paris Hilton", he claims that footage exists of her "in a state of arousal in a New York taxi."

In other news, it seems Paris is following in Lindsay Lohan's footsteps, turning her attention to women instead of men. Hilto was reportedly seen lavishing attention on model Cheyenne Tozzi as they travelled across Australia's Gold Coast, Sydney and Byron together. The two are said to have become close when Paris lost her camera at a Sydney nightclub on New Year's Eve.

There's nothing like a sex tape and hints of lesbianism to recapture the gossip world's attention.
