Kourtney Kardashian rows with Rob

Kourtney Kardashian rows with Rob

Kourtney Kardashian claimed her brother Rob Kardashian threatened to publicly brand their family "disgusting" after they had a row.

The 'Keeping Up With the Kardashians' star was upset when her sibling's fiancee Blac Chyna - who has a three-year-old son King Cairo with ex-partner Tyga - released an emoji in her Chymoji range of a girl getting slapped which looked very similar to her half-sibling Kylie Jenner.

But after Kylie - who is in a relationship with Tyga - told her not to call pregnant Chyna, Kourtney decided to let her feelings be known to Rob instead.

In a preview clip from 'Keeping Up With the Kardashians', Kourtney, 37, 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."

And later in the clip, Kourtney told their sister Khloe Kardashian: "I went off on him yesterday. He was like, 'I'm going to go on the red carpet tonight and I'm going to tell everybody how I have the worst, most unsupportive, disgusting family!' Like, ridiculous. I think that it's stupid to take it there."
