We’ve all heard of latch-key kids, but backdoor teen moms? That’s a new one. (That’s a gross one.) It’s also the name of former Teen Mom “star” Farrah Abraham’s sex tape with porn star James Deen. “Farrah Superstar: Backdoor Teen Mom” will be available for online viewing (ugh) tomorrow from Vivid Entertainment. (Side note: Abraham locked down a seven figure deal for this tape. Seven. Figures.) And — surprise, surprise — stills from the tape have already leaked online courtesy of TMZ.
