The reality star was furious her sister initially didn't want to appear as a character in her mobile game

This season of Keeping Up with the Kardashians doesn’t just have the Jenners divided against the Kardashians – it also has the Kardashians divided amongst themselves.

On Sunday’s episode of KUWTK, we see some of the process that Kim Kardashian West underwent when making her wildly successful mobile game, Kim Kardashian: Hollywood.

Though Kourtney Kardashian now appears in the game, she initially had no interest in appearing – much to Kardashian West’s annoyance.

“It’s ridiculous for you to just not do that for me as a favor, because I’ve done so much for you,” Kardashian West, 34, says of her sister, 35, in this week’s episode, as seen in the above clip. “And for Scott [Disick] to call me and say, ‘You should buy her a pair of shoes to put her character in the game,’ I’m like, ‘Buy her a pair of shoes? All the s— I’ve done for her?’ ”

Adds Kardashian West, explosively: “I said to Scott, ‘I’m not buying her a f—ing pair of shoes – I bought her a f—-ing career!’ ”

Kardashian did not appear impressed by her sister’s outburst.

Keeping Up with the Kardashians airs Sundays (9 p.m. ET) on E!
