Kim Kardashian Says She 'Bought' Kourtney Her Career

Things get heated between the sisters on "KUWTK."

When Kim came out with her wildly successful game "Kim Kardashian: Hollywood," apparently Kourtney didn't want to be involved.

This didn't sit well with the 34-year-old reality star.

"I don't want to be in your video game," Kourtney yells, in a clip obtained by People magazine.

"It's ridiculous for you to just not do that for me as a favor, because I've done so much for you," Kim replies to her older sister. "And for Scott [Disick, Kourtney's partner] 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 f------ pair of shoes? All the s--- I've done for her?'"

Kim adds, "I said to Scott, 'I'm not buying her a f---ing pair of shoes, I bought her a f------- career!'"

The clip ends after that, but by the looks of Kourtney's face, it's about to get even more heated.

The episode airs Sunday at 9 p.m. EST on E!
