Kourtney Kardashian says she may change her kids’ last name so Blac Chyna's kid won't be the only Kardashian

On Sunday's episode of  Keeping Up With the Kardashians, it seemed like the Kardashian clan don’t want Blac Chyna to carry on their family’s last name. The Kardashians were deeply offended when they found out through social media that Rob Kardashian had proposed to Chyna without bothering to tell them and that she was pregnant.

During dinner, on the show,  Tyga.(Blac Chyna's ex and Kylie Jenner's bf) said of Blac Chyna:

“She’s gonna carry on the legacy, like if she has a boy."

To which Kourtney Kardashian responded:

“I could change my kids’ last names,”

Talking about her 3 children, Mason Disick, Penelope Disick  and Reign Disick.

That clearly upset Kourtney's baby Daddy, Scott Disick who said:

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

Kourtney then changed her tune and said she was only joking.
