Porn Superstar James Deen Confirms 'Sex Tape' with Teen Mom Farrah Abraham

Asked about her participation in a recently shot "sex tape," MTV reality show personality Farrah Abraham pretended to know nothing about it.

"I don't ... exist ... anything about that," she told TMZ.

The Teen Mom — who hasn't been a teen for a while — even fake-threatened to get litigious.

But the chances of that happening are effectively zip considering the whole thing is a rather poorly engineering marketing campaign for the "aspiring model's" first commercial porn film.

Exhibit A-Z: The so-called "sex tape" co-stars the adult film industry's leading man du jour James Deen, and according to him, was shot on a porn "set" last Friday.

Through its incestuous pipeline to Vivid Entertainment, TMZ "learned" that the same studio that brought you Kim Kardashian's career is doing everything it can to secure the rights to the tape.

"It's amazing," Vivid CEO Steve Hirscho told TMZ about the porn, which allegedly contains 30 minutes of "full-on sex."

Abraham, who has a four-year-old named Sophia, has been spending her post-Teen Mom time boozing it up in lingerie, getting busted for DUI, and blaming it on being unable to "blow properly" due to an illness.
