The "Teen Mom" star has been in a war of words with Deen ever since he told us that Farrah's "sex tape" was really just a porn shot at her request.
Farrah took a below-the-belt shot at Deen while talking to our photog yesterday ... which is ridiculous and gross -- ridiculous because he's a male porn star (um, hello!?!?!?) and gross because her mom was standing there the whole time.
The video won't embed but I highly recommend that you go to the source and watch it. The delusion shared between her and her mother here is so amazing I seriously cannot. Farrah compares her porn to a wedding video. Her mom says Farrah didn't know they were actually making a video. I can't.
