Kourtney Kardashian desires to carry on the loved ones legacy! On this week's episode of Maintaining Up with the Kardashians. the family members found out the news of Rob Kardashian and Blac Chyna 's pregnancy whilst vacationing in Colorado — and Kourtney wasn't as well pleased with the thought of Rob and Chy's little one carrying on the Kardashian title. On the show, Tyga said that if Chyna has a boy, he can very properly carry on the name, to which Kourtney responded, “I could modify my kids' last names!” (Photo Credit score: Photographs) Scott Disick. who was obviously not pleased with Kourtney's rash response, swiftly fired back, “What the f--k? I'm sitting you sick f--k!” The reality star sooner or later gave in and explained it was all jokes, but she had every person quite fooled for a minute. It seems as however the Kardashians have welcomed the expectant model with open arms — just final night she was out with her future in-laws celebrating Khloe Kardashian 's 32nd birthday bash.
