Kourtney Kardashian admits Kim made her cry when she called her the 'least exciting to look at': 'I took it really personally'

• Kourtney Kardashian told sister Kylie Jenner that an insult from Kim Kardashian once made her cry.
• The eldest Kardashian was referring to a 2018 argument that led to Kim commenting on her appearance.
• "Oh my god, I was literally crying," Kourtney told Jenner about the insult.

Kourtney Kardashian revealed in a new video with sister Kylie Jenner that an insult from Kim Kardashian West once made her cry.

Jenner was doing the elder Kardashian's makeup for her YouTube channel when she brought up the viral fight Kourtney and Kim had in 2018.

"So I need to know how you really feel about - in the moment - Kim saying you were the least interesting to look at," Jenner said (around the 7:24 mark in the video below).

"Oh my god, I was literally crying," Kourtney said. "At the time I took it really personally, and I was like, 'Why would someone in my family say something like that?'"

The sisters agreed that the moment later "turned into such a thing," and Kourtney said that she was eventually able to "laugh" at the argument.

During her conversation with Jenner, Kourtney even called Kim to ask for her take on the situation.

"That was such a low blow," Kim said of her insult.

The argument, which later aired on a 2018 episode of "Keeping Up With the Kardashians," saw Kim and Kourtney get into a fight after Kourtney refused to rearrange her schedule to accommodate Kim's photo shoot.

After a heated exchange, Kourtney left the room where Kim was trying to plan the shoot.

"She's the least exciting to look at, so she can be out," Kim said as Kourtney walked away.

Kim later clarified what she meant by her comment (which later became a meme, though Kim is often misquoted as calling Kourtney the "least interesting" to look at) during a subsequent episode of "KUWTK."

"We got into a fight. I said, 'You're the least exciting to look at,'" Kim told Kourtney. "What I meant is, you're the most boring."

Kourtney seemed more bothered by the backlash she'd received from fans than by Kim's insult.

"Someone wrote this thing, like, 'You should thank Kim for your career,'" Kourtney said.

"But I was gonna write back and say, 'If it wasn't for my personality and being funny, then our show wouldn't exist,'" she added.
