Crazy memories! Khloé Kardashian posted a throwback Keeping Up With the Kardashians clip of her siblings Kim Kardashian and Rob Kardashian fighting on Instagram on Saturday, April 9.

In the heated clip, Kim, 35, stands poolside in a bikini and tells her younger brother, “You’re a dick. You have no manners.” Rob, 29, angrily replies, “You’re a whore. You have no manners.”

“I’m a whore?” she asks, before he responds, “You just called me a dick, so I’m going to say something right back.”

“He’s so immature,” Kim says, laughing. The siblings’ stepfather, Bruce Jenner (who transitioned into Caitlyn Jenner last year), walks over, prompting Kim to call for backup. “As a dad, you should step in because he’s being disrespectful,” she tells Bruce.

“MOOD!!!” Khloé captioned the video on Saturday. “I wish all fights were like this. What were they even fighting about?”

Earlier in the week, Rob announced his engagement to girlfriend Blac Chyna while the rest of the Kardashian-Jenner family boarded a private plane to Colorado. As Us Weekly previously reported, they haven't publicly commented on the proposal and think Rob is “making a mistake.”

“Kris is not happy,” an insider told Us. “Dating Chyna is one thing, but marrying her is another … The whole family is discussing it and is angry, but they are talking to come up with a unified front for how to address it … It’s a huge mistake to them.”

Khloé hasn’t spoken out much about Rob and Chyna’s relationship, which started in late January. She recently said on an episode of Kocktails With Khloé that things are “very dramatic” between her and her brother’s girlfriend.

“It’s like a soap opera episode, so it sounds very dramatic, which it is,” she admitted. “But I actually haven’t seen Chyna in a few years, but her and I did not get into a fight, but I do love a good fight.”

A source told Us in January that Khloé felt “majorly betrayed by Rob after she always stuck up for him. She feels like this is a major blow to the family. Nobody in the family likes it.”

Thank You!
