The 38-year-old rapper and fashion designer was fuming over Kylie's decision to book a modeling gig with Puma after having worked with Kanye on his Yeezy Boost sneaker line for Adidas.
"Kanye had Kylie walk in his first two shows," Kim Kardashian explained in the episode. "He really believed in her as part of his brand."
Kanye was clearly upset by the news, comparing it to agreeing to star in his own reality show without telling anyone on KUWTK.
"It's like if I made a show Sunday night, and didn't tell any of you all about it, but I did a couple shows with y'all [first]. So people saw me and were all, 'Ah, he's cool on camera.' And somebody offered me a deal, and I, like, did it and didn't tell none of y'all, and brought all my cool friends," Kanye vented.
"I don't agree with going against the family," Khloe agreed, placing some of the blame on the shoulders of their mother, Kris Jenner, who serves as Kylie's manager, explaining, "Mom and or Kylie should have presented it to Kanye first."
Kim admitted to the cameras that she appreciates that it's her mom's job to find modeling deals for Kendall and Kylie, however "everything has to be really carefully played out and I feel like this was a conflict of interest."
When they returned to L.A., Kim confronted Kris about how the situation was handled, and chastised her for going behind Kanye's back.
"Sometimes it's about a business decision," Kris said, arguing that she's responsible for getting the best deals for "each one of my clients."
"Sometimes, when you're dealing with family, it's not really about a business decision," Kim retorted.
According to Kim, Kanye had no idea that the deal had even been made until "the shoot was already happening," and that Kylie was the model Kanye truly wanted for his line.
"I am just trying to do the best job for everyone that I can," Kris said, before admitting, "Sometimes I get ahead of myself and forget to communicate the way I should."
While there was an amicable conclusion to Kim's beef with Kris, Kanye was much more vocal at the time.
In February, the business mogul took to Twitter to rail against Puma, writing in a series of posts, "1000% there will never be a Kylie Puma anything. That's on my family! 1000% Kylie is on Yeezy team!!! Puma we gone give you your measly million dollars back!!! Never try to divide the family!!!"
