Kim the peacemaker. Kim Kardashian urges her sister Kourtney to make up with their brother, Rob, in Sunday’s episode of Keeping Up With the Kardashians. In a sneak peek of the Sunday, August 21, episode, the Selfish author tells her older sister she needs to call Rob to settle their ChyMoji feud.

“Did you get a chance to talk to Rob?” Kim asks Kourtney.

"I haven't really talked to him since we got into that fight when I yelled at him," Kourtney tells her.

“I can’t believe he hasn’t cared enough to call you … I feel like this is so ridiculous, and we all need to get over it,” Kim says.

"Well, I know what it's like to be having your first baby and people aren't supportive," Kourtney says. "It took like years for people to like Scott."

"True," Kim replies. "But I just wanted to at least get you guys on the phone so we can not have any kind of drama."

As previously reported by Us Weekly, Kourtney went HAM on Rob over his fiancée Blac Chyna’s ChyMoji that resembles their younger sister Kylie Jenner getting slapped.

"This was the first time that made me question Chyna's intentions," Kourtney told the camera about her brother's pregnant fiancée in a previous clip. "Like, I usually don't let any of this stuff bother me, but for some reason this just sets me off."

The family has since mended their drama with Chyna, who is expecting her first child with Rob this fall. Their beef stemmed from the fact that Jenner started dating Chyna’s ex-fiance Tyga, after the makeup artist split from the rapper in 2014.

Watch the clip above. Keeping Up With the Kardashians airs on E! Sundays at 9 p.m. ET.
