Kim Kardashian Sex Tape -- Kris Humphries Claims Kris Jenner Staged It

Kris Humphries trashed Kim Kardashian and her family in conversations and text messages to his former girlfriend, Myla Sinanaj ... telling her Kris Jenner not only directed Kim to shoot her sex tape, but to re-shoot because Kris J didn't think the first one was pretty enough.

As TMZ first reported, Kim has subpoenaed Myla in Kim's divorce case, and we've learned Myla has a lot to say about what Kris told her about his relationship with his famous estranged wife.

In addition to the sex tape, sources tell us Myla has numerous text messages in which Kris says she is the love of his life and he wants to get the divorce over with quickly so they can spend the rest of their time on earth together. In several of the messages, we're told Kris says specifically that he's "moved on" from Kim.

The information is extremely damaging to Kris, because he's alleging in his divorce that Kim has destroyed him emotionally by allegedly defrauding him into believing it was a real marriage. Turns out, Kris has been banging Myla since mid-January, so his devastation argument may be hard to swallow.

Sources close to the Kardashians tell TMZ ... Kris is lying about the sex tape. They say Kim made it clear at the beginning of their relationship she would not discuss the tape because she didn't want to be judged by it. Our sources say the sex tape never came up in any subsequent discussions between Kim and Kris and it just shows he's delusional.
