Rumor has it there’s another Kardashian sex tape being shopped around…….and it’s not a tape of Kim, Kourtney, or Khloe- it’s of their mom, Kris Jenner!!!! There’s supposedly a Kris Jenner sex tape from the 80s floating around. Kris was married to the Robert Kardashian at the time, but he’s not featured in the tape. (Kris was cheating on her husband at the time with Todd Waterman.) According to a source, "Robert [told good friend O.J. Simpson] that Kris was talking about how liberating it was to be filmed having sex and how it was a turn-on to watch herself with her lover [not Robert]. She said she felt like a porn star. When Robert heard that, he confronted Kris. But she laughed it off, telling him she was just kidding around. She said she knew he was there and wanted to teach him a lesson about eavesdropping on her conversa­tions with her girlfriends. Robert wasn’t sure what to believe, so he told O.J. about it to see what he thought.Back in the day when she was cheating on Robert, Kris was capable of anything. If a Kris Jenner sex tape is released, it could destroy the Kardashian brand and be the final straw for her mar­riage to Bruce, which is already hanging by a thread.”
