People.com Entertainment TV Kim Kardashian Wants Kourtney to Make Up with Rob After Blac Chyna Blowout: 'This Is So Ridiculous' Kourtney and Rob fought over Blac Chyna's rumored ChyMoji diss at Kylie Jenner By Aurelie Corinthios Updated on December 2, 2020 01:59 AM Share Tweet Pin Email Photo: E! Kim Kardashian West is playing peacemaker. In a sneak peek at Sunday’s episode of Keeping Up with the Kardashians, Kim tries to smooth things over between her siblings Kourtney and Rob Kardashian after the two got into an explosive argument over Rob’s fiancée Blac Chyna. “I haven’t really talked to him since we got into that fight when I yelled at him,” Kourtney, 37, tells Kim, 35, in the clip. “I cannot believe you haven’t talked to him since then and I cannot believe he hasn’t cared enough to call you,” Kim replies. “I feel like this is so ridiculous and I think we all just need to get over it. You know?” Kourtney goes on to say that of all people, she thinks she’s the one Rob, 29, who is expecting a child with Chyna, 28, should be able to relate to the most. “I know what it’s like to be having your first baby and people aren’t supportive,” she says. “It took years for people to like Scott [Disick].” “I just want to at least get you guys on the phone so we can not have any kind of drama,” Kim says, deciding to call up their brother.

I just want to hear what Rob says. I’m hoping that he wants to make it a peaceful situation as well.” Keeping Up with the Kardashians airs Sundays (9 p.m. ET) on E!
