The 'Keeping Up With the Kardashians' star decided to play peacemaker between the two after they fell out in a row over the reclusive sock designer's fiancee Blac Chyna's Chymoji emoji icons, which featured a girl resembling their younger half-sister Kylie Jenner getting slapped.

Kim, 35, asked Kourtney if she had spoken to Rob, 29, and she replied: "I haven't really talked to him since we got into that fight when I yelled at him."

Kim then replied: "I cannot believe you haven't talked to him and I can't believe he hasn't cared enough to call you.

"I feel like this is so ridiculous and we all just need to get over it."

Kourtney - who has children Mason, six, Penelope, four, and Reign, 20 months, with former partner Scott Disick - insisted she sympathised with Rob, who is expecting his first child with Chyna, because of her own experiences when she was pregnant with her oldest son.

In a preview from an upcoming episode of 'Keeping Up With the Kardashians', she said: Well I know what it's like to be having your first baby and people aren't supportive. It took like years for people to like Scott."

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

Kim - who has kids North, three, and Saint, eight months, with husband Kanye West - then called Rob on Kourtney's behalf, but the trailer ends before anyone picked up.

As Kim let the phone ring, her older sister admitted she wanted a "peaceful situation" for the family.

She said: "I think Kim is right, I should have asked Rob what was going on instead of just getting so angry and assumed certain things were true and I just want to hear what Rob say. I'm hoping that he wants to make it a peaceful situation as well."

Kourtney's row with Rob was explained in a preview clip earlier this week.

The 37-year-old star told her make-up artist Mario Dedivanovic: "Everything with Rob, I always try to be super calm but I was just like in a mood.

So, I was gonna call Chyna and then Kylie was like, 'No just call Rob, it's too crazy to call Chyna.' And I'm like, 'I don't want to yell at a pregnant person.' "

Though the brunette beauty has been supportive of Rob and Chyna's relationship, she admitted the icons had made her question the make-up artist's "intentions".

She added: "This is the first time that made me question Chyna's intentions. I usually don't let any of this kind of stuff bother me, but for some reason this just sets me off."

But Rob didn't take her comments well.

Kourtney recounted: "He was like, 'What do you care if she's doing this, everyone has emojis!'

"And I don't care that she has them, I care that it was Kylie."
