Rob To Kris: I Quit! Kardashian Jumping Ship After Blac Chyna Trademark Diss

Kris Jenner is in major damage control mode after the family's lawyers dished out a humiliating legal slap to Blac Chyna over her plans to trademark the family name. But RadarOnline.com has learned that it may be too little, too late!

"Kris went over to Rob and Blac's house to try and make everything right, but Rob blew up on her when she got there because he believes that she was responsible for this," a source close to the family told RadarOnline.com. "Rob is certain that Kris was actually behind the whole entire thing."

According to the source, "After Rob went off on his sisters, they told him that the whole thing had been Kris's idea and that they really had nothing to do with it. Kris was the one that directed the lawyers to take action."

"Kim, Kourtney and Khloe really couldn't care less about Blac Chyna using their name once she marries Rob. It's true that they are not that fond of her, but they also know that she makes their brother happy and that is all that they are really concerned with," the insider told RadarOnline.com.

But the insider said that Kris "has a different agenda."

"Her only concern is protecting the brand," the source claimed. "Rob has had enough of her manipulations, and he told her that if she ever tries to pull anything like this again, he will quit the show and she will NEVER see her granddaughter, Dream, again!"
