Teen Mom star Farrah Abraham has vehemently denied she features in a sex tape currently being shopped around Hollywood, though has also threatened legal action against those in the possession of the alleged clip. 21-year-old Abraham was shopping at lingerie store Agent Provocateur in Los Angeles this week when she was asked by a TMZ cameraman if she knew about the existence of the tape.

"I don't ... exist ... anything about that," she said in reply - which makes absolutely no sense at all. She later changed her position, saying, "If I had my own personal stuff, that's my own personal thing." During the encounter, Abraham seemed nervous and failed to understand my of the question, finally saying "if there's someone being rude and trying to get at me, then my lawyer will take care of that." When it's suggested that it could further her career in the same way that adult films helped Kim Kardashian and Paris Hilton, Abraham said she worked hard and didn't need a sex tape to help her get where she wants to be.

The alleged tape featuring the MTV star is being shopped around various adult movie companies, including Vivid Entertainment. Steve Hirsch, president of Vivid, confirmed to TMZ.com that he saw the video and that Farrah very much features in it for around 1 hour.
