Most would agree that Kim Kardashian became a household name with the 2003 release of her infamous sex tape with then-boyfriend Ray J. In a new book about the Kardashian-Jenner family, author Ian Halperin alleges that Kardashian’s mother, Kris Jenner, was the mastermind behind the X-rated video becoming public.

Page Six reports that Halperin’s book, “Kardashian Dynasty: The Controversial Rise of America’s Royal Family," claims Kardashian signed a deal with porno studio Vivid Entertainment in 2007 to have the tape released. “A mutual friend of Kim and Paris [Hilton] had advised her that if she wanted to achieve fame, a sex tape would be the way to go,” Halperin wrote. “Kim had discussed the idea of producing a tape with her family beforehand.”

The book, which will be released in April, also alleges that a close friend of Kardashian’s said it was Jenner who “engineered the deal behind the scenes” and was “responsible for the tape seeing the light of day.”

Halperin talked to a Vivid Entertainment representative about Kardashian and Ray J’s tape, writing that the unnamed source confirmed that both parties involved have to sign off before the company can release the tape.

“A third party brought it to Vivid. … [We] got in touch with the Kardashian family,” the rep said, according to the book. “Kim Kardashian’s movie came out in '07, and she’s made millions.”

Earlier this month, Kardashian wrote a blog post questioning why so many people still liked to bring up her sex tape. “I don’t do drugs, I hardly drink, I’ve never committed a crime — and yet I’m a bad role model for being proud of my body? It always seem to come back around to my sex tape,” she wrote (via Us Weekly). “Yes, a sex tape that was made 13 years ago. 13 YEARS AGO. Literally that lonnng ago. And people still want to talk about it?!?!”

She continued, “I lived through the embarrassment and fear, and decided to say who cares, do better, and move on. I shouldn’t have to constantly be on the defense, listing off my accomplishments just to prove that I am more than something that happened 13 years ago. Let’s move on, already. I have.”

In 2013, Jenner opened up about her daughter’s explicit video, telling Jon Rivers on her show “In Bed With Joan” that she “literally fell apart” after it was released.

“I cried myself to sleep,” she told Rivers, who died in 2014. “I don’t think anything can prepare you for something like that when it comes to your daughter.”
