Is the Kardashian brand in a deep dekline? It seems that several of the family's in-the-works projects are no longer in the works.

The New York Post is reporting that Kris Jenner's demands have killed a deal that would have seen publishers American Media Inc., the company behind The National Enquirer and Star, creating a Kardashian-themed magazine.

Sources say that mama Jenner tried to play hardball with the publishers, demanding that she get full editorial approval when it comes to Kardashian-related content in any and all of the magazines the company publishes.

"AMI chief David Pecker made it clear that there was no way he was going to tell his editors what stories they could and couldn't do," a source explained, adding that the company "balked" at her stipulation. Perhaps in response, Star magazine recently published a cover story claiming that the late Robert Kardashian is not Khloe's biological father.

Speaking to MTV News, a source close to the negotiations took no issue with the accuracy of the story, hinting that the deal is indeed dead in the water. A rep for the family told the Post, "Kris has never had a conversation with AMI regarding this issue [of her demands]. But the allegations contained in the Star article about Khloe not being a Kardashian are completely fabricated, false and untrue. Robert Kardashian is absolutely her biological father, so of course she was upset over their story."

It's not the only blow the Kardashian brand is being dealt. According to previous reports, the ladies had been in talks with Mattel to work on their own Kardashian-themed Barbie dolls. It seems, however, that those plans have also been shelved.

A rep for Mattel told MTV News, "As popular as the Kardashian sisters are, at this point in time we are not manufacturing Barbie-branded Kardashian dolls."
