Kylie Jenner Threatens to Fire Kris if She Doesn't Stop Rob Kardashian, Blac Chyna Dating

World War III is brewing in the Karadashian-Jenner household. Little sister Kylie Jenner has been upset since Rob Kardashian began dating family rival Blac Chyna -- and she's threatening to punish momager Kris Jenner if she doesn't do something about it.

Kylie is dating Chyna's ex, Tyga, and it's all a little too close for comfort. But Kris might not care one way or another --  Radar Online is reporting that she is backing Rob in the battle. 

"Everyone in the family just feels like Kris is taking Rob's side in this situation," an insider told the  site.

Kylie is upset about a recent post to Rob's Instagram account regarding his relationship with Chyna that dissed his whole family.

Rob posted an image with the caption: "When the p**sy good but your family don't like her so you drop your family and become an orphan."

"Kylie told Kris that she is going to fire her and find different management because she thinks that Kris allowing Rob to post things like this is just ridiculous," an insider told The Hollywood Gossip. "But Rob and Kris are tighter than they have been in years, and Kris refuses to do anything to stop him. She is just really grateful that her son is healthy, happy and has gotten out of his funk."
