'KUWTK': Kourtney Kardashian Says She Could Change Her Kids' Last Names So Blac Chyna Won't Have the Sole Kard

Awkward! It looks like the Kardashians don’t want Blac Chyna to carry on their family’s name. On Sunday’s episode of Keeping Up With the Kardashians, the family was deeply offended when they learned via social media that Rob Kardashian had proposed to Chyna without bothering to tell them.

In previously released clips, fans saw the stunned reactions Rob’s sisters had to the news, but in Sunday’s episode, Kourtney Kardashian took it a step further while on the family’s trip to Vail.

After offering to be the first one to reach out to Chyna, calling herself “the rational one,” the eldest member of the Kardashian-Jenner clan got personal at dinner while talking to Kylie Jenner’s on-again, off-again boyfriend (and Chyna’s ex) Tyga.

“She’s gonna carry on the legacy, like if she has a boy,” Tyga said of the now-pregnant Chyna.

“I could change my kids’ last names,” Kourtney replied, referencing her three children – Mason, Penelope, and Reign Disick.

“What the f**k, I’m sitting right here you sick f**k!” Scott replied.

Clearly the father of three was not pleased by Kourtney’s suggestion. She went on to clarify that she “could change” her kiddos last names “so that she couldn’t have the last name.”

Scott replied, “What the f**k is wrong with you?” to which Kourt insisted, “It’s a joke!”

This isn’t the first time someone in the famous family has toyed with a possible name change. Momager Kris Jenner considered reverting back to the Kardashian last name even while she was still married to her now-ex Caitlyn Jenner.

Though the reality star gang seemed upset by Rob’s proposal, it sounds like they're still going to the wedding. In the words of Kourtney: “How many weddings have we been to in this family and they don’t mean s**t so let’s all get it over with.”
