kris and khloe*“Keeping Up With the Kardashians” matriarch Kris Jenner is the one responsible for daughter Khloe Kardashian losing her co-hosting job on “The X Factor,” if you believe gossip pro Perez Hilton.

According to his website, Jenner insulted Khloe’s former “X Factor” co-host Mario Lopez by suggesting that one of her other daughters replaces him on the show – so that two Kardashians would serve as co-hosts.

“Everyone thinks that Mario hated working with Khloe. But he was nothing but encouraging and supportive (to Khloe). It was her mother Kris who was the problem,” a source explains. “Kris would go to the producers and say Mario was being pushy and insensitive and she’d often confront Mario directly. There was even a very absurd incident when Kris suggested to the producers that they should dump Mario and replace him with one of her other daughters. Kris claimed that the chemistry between Mario and Khloe just didn’t work and that Kim or Kourtney would be a better fit.”
