LOS ANGELES – The girl who hooked up with adult star James Deen in Vivid’s Superstar Farrah: Backdoor Teen Mom is tired of porn now, thank you. In the current issue of Life & Style, former MTV Teen Mom Farrah Abraham announced she wants to become a nun.

Or a virgin. Possibly both.

“People use sex for power and manipulation, when sex is supposed to be enjoyable and great,” Abraham told Life & Style. “I don’t feel that. I want to be a virgin forever — or a nun.”

Pardon us for pointing this out, but hasn’t the chastity horse already left the barn?

The interview just happens to coincide with Vivid Entertainment’s release of a second Abraham-Deen sex tape. Farrah 2: Backdoor and More features previously unreleased footage shot during the studio session she requested and shamelessly promoted.

“So much that happened wasn’t in the first movie,” Deen told Celebuzz.com. “Half the video wasn’t used, so I was wondering when [Vivid would] release it.”

Although Deen was happy to charm the pants — and every other stitch of clothing — off Abraham after she selected him as her co-star for the Vivid-lensed flicks, he appears to have had enough of her publicity-seeking antics and bizarre mood swings.

“It got so dramatic and annoying with all the publicity stunts, so I prefer to stay out of [promoting the second video],” Deen told Celebuzz. “I want it to go away.”

Meanwhile, TMZ.com has called Abraham’s sincerity into question (again) by posting a redacted version of what are alleged to be email negotiations between Vivid honcho Steve Hirsch and “reluctant” porn star Abraham.

Abraham claimed “she never approved a sequel,” TMZ posted. “Small problem … We have an email Farrah sent to Vivid … in which she gives the porn company the right ‘to release video or videos(s).’ Plural times 2.”

So much for reluctance.

For her part, Abraham now claims Deen and porn ruined her sex life: “I don’t feel like sex is what it used to be,” she told Life & Style.

Whatever that means.
