Nicole Richie and Paris Hilton Porn Movie in the Works

And to think, Paulina James thought she had the celebrity porn movie world all to herself.

The adult film star, who will be portraying Lindsay Lohan nude in an upcoming flick, now must deal with the fact this sex-filled spoof won't be the only title of its kind coming out in the near future.

Venom Digital Media is releasing Paris and Nicole Go to Jail in September, a very x-rated version of the thin stars' jail hijinks.

Sindee Jennings and Aubrey Addams (what, was Kendra Jade unavailable?) will be filling the talentless, law-breaking shoes of these socialites, as they find "that life is different on the inside, and at first have trouble adapting, but soon learn how to get things in prison by becoming friendly with the warden, the guards, the inmates."

We think Stavros Niarchos is familiar with how Hilton goes about doing that!

Nicole Richie is pregnant now, of course, so she may wish to keep her future child away from the porn aisles when he or she gets older.

As for her skanky friend, well, a Paris Hilton sex tape is nothing new. This one just won't be starring the spoiled heiress herself is all.
