It's not hard to see why she's less than thrilled!

Kris Jenner and boyfriend Corey Gamble caught a flight out of LAX over the weekend, and the look on the momager's face said it all when we asked her about Rob Kardashian's recent engagement to Blac Chyna. This whole thing is pretty much the family matriarch's worst nightmare, and it doesn't help that her only son is jeopardizing her relationship with E! by shopping around a wedding docuseries to other networks!

The controversial couple could bank $150-$200K each per episode, as well as $500K each for the wedding day episode, TMZ reports. This is worse than when Kim decided to tie the knot with Kris Humphries! The fact that Chyna wants to take the family name has got to be sending Kris into an actual panic.

The powerful 60-year-old might want to double her efforts on getting in the way of the "I Do's," because they have already started planning the nuptials! "Chyna will have at least two dresses on her wedding, both statement pieces. [She] has an idea on who she may want to design her dresses. Her makeup will be flawless and she will be using all her products," a source dished to E!. "Chyna loves the warm weather, so the ceremony will be outside and somewhere in a warm climate. [She] wants a big wedding with all her friends and family, and then a fun party after the ceremony," the source added.

Rob's getting his revenge after years of being bullied by his sisters and mom!
