U.S. reality Tv star Farrah Abraham regrets baring all for a 2013 sex tape encounter with porn star James Deen, because the shocking film has robbed her of true friends.

The Teen Mom 2 star became an overnight X-rated sensation when Farrah Superstar: Back Door Teen Mom was released, but now she admits she would not have made the adult film if she had known of the repercussions.

She tells In Touch magazine, "It made it hard to have friends and a private life and to trust family, who I feel use me for money. If I went back in time, I would not have done it. The sex tape ruined my life.

"Knowing my sex tape was out there for everyone in the world to see... was overwhelming. I wanted to hide my face and not go out or pick up my phone."

Abraham has even tried therapy to help her deal with the fall-out following the sex tape, adding, "Therapy helped me understand... that I'm more special than sex tapes."
