Kardashian EXCLUSIVE!!

It's official! Everyone can stop wondering who released Kim Kardashian's sex tape to the public. I have the answer for you.. WELL IT WAS KIM'S OWN MOTHER KRIS!!

Yes Kris did it! That's some motherly love for ya huh?

Here's what STAR MAGAZINE is reporting:

"Kris was totally involved in arranging the sale of Kim's tape," claims the source. "The video already existed, and Kris was there every step of the way as a middleman - [she] was brought in to market it to an adult entertainment company." The tape was ultimately released for sale by Vivid Video, which reportedly paid $1 million for the rights."

We know what you're thinking . . it's STAR MAGAZINE, how do you know it's true. Well peep this:

The source - who PASSED A POLYGRAPH TEST at Star's request - claims: "I saw Kris Signature on the contract; I believe she got somewhere between $250K and $500K for the original deal."

Shame on you Kris!!
