Kardashians In Khaos! Tantrums, Meltdowns & More After Rob Scores Blac 'KUWTK' Contract

RadarOnline.com has exclusively learned that the Kardashians and Jenners are absolutely besides themselves now that Rob Kardashian is getting Blac Chyna an official contract for the family reality show Keeping Up with the Kardashians.

"Obviously, Rob wanted his mom," Kris Jenner, "to give Blac a contract to appear on the show since she is going to be a permanent part of his life now," an insider told RadarOnline.com.

And so far money-hungry Jenner is open to the idea! "She's considering it because she knows how much interest and new storylines they could generate," noted the insider.

While letting the two appear on the show could be great for ratings, it's bad for 18-year-old Kylie Jenner's nerves.

"Kylie is threatening to quit over this because she refuses to have to fake her feelings for Blac," revealed the insider. "Kylie cannot believe that Kris would even possibly consider this, but it is very real possibility now."

Part of the problem, continued the insider, is that the youngest Jenner, whose boyfriend Tyga has a child with Chyna, 28, can't stand she will go from "all the audience wanted to see" this season to pushed aside as her 29-year-old brother and arch-nemesis' relationship takes center stage.

As RadarOnline.com reported, Kardashian recently asked Chyna for her hand in marriage with a stunning 7-carat ring, despite the fact his loved ones can't stand Chyna.
