"Teen Mom" Farrah Abraham got down and dirty while cameras rolled and now a sex tape is being shopped to various porn companies featuring the MTV star ... TMZ has learned.
According to sources who have seen the tape, Farrah and a male partner (possibly her ex-boyfriend) go at it for about 30 minutes ... full-on sex ... in various positions. We're told it was recently shot.
Our sources say the person selling the tape has already shown it to some of the biggest XXX companies and is looking to make a deal.
It's another notch in Farrah's belt ... she was recently snapped boozing it up in nothing but lingerie. And last month she was arrested on suspicion of DUI, when cops say she blew nearly twice the legal limit.
Sweet, she was the hottest one
It's twue, it's twue ... it's reawwy twue ... James Deen's gargantuan penis IS the co-star in the Farrah Abraham sex tape ... at least according to James Deen.
Deen -- a professional porn star -- tells TMZ, "Word travels fast ... it isn't even edited yet. We shot it yesterday."
When asked if the two were dating, based on the fact they were seen holding hands yesterday, Deen said, "Definitely not dating. Got tested together on Friday and then saw her on set. That is my only experience with the lady."
As we first reported, the XXX footage is being shopped around to various porno companies -- including Vivid. We spoke to Vivid honcho Steve Hirsch who tells us he's seen the entire tape and says, "It's amazing ... and I'm doing everything in my power to get the rights to put it out."
