Kourtney Kardashian says social media users "hate" Kim Kardashian West for her insulting comments on 'Keeping Up with the Kardashians'.
The 38-year-old reality star argued that Kourtney, 39, was the "least exciting to look at" of her sisters, and in a teaser clip from an upcoming episode of the show, Kourtney is seen reacting to the online backlash against Kim.
Speaking to Kim and her ex-boyfriend Scott Disick, Kourtney quips: "Oh my god, people are going so crazy. People hate Kim from her comment on the show."
Kim - who is married to rapper Kanye West - subsequently tried to clarify her offensive remarks.
The American star explained: "We got into a fight. I said, 'You're the least exciting to look at.'
"What I meant is you're the most boring. People think that is like I said, 'Kill your mom.'"
In the clip, Kourtney insists they should not seek to "justify" their spat.
But Scott - who has kids Mason, eight, Penelope, six, and Reign, three, with Kourtney - comes to the defence of Kim.
He said: "But that's your sister! You say bad things about her too. You call her a porn star every time I talk to you."
Another social media claimed Kourtney ought to feel grateful towards her younger sister for helping to make 'Keeping Up with the Kardashians' a worldwide success.
In response, Kourtney quipped: "I was gonna write back and say, 'If it wasn't for my personality and being funny then our show wouldn't exist.'"
And Scott - who split from the brunette beauty in 2015 - added: "Ha! For sure, without you this whole thing would be dead."
