— -- In a teaser for Sunday's upcoming episode of "Keeping Up with the Kardashians," the gloves come off between Kim Kardashian and her sister Kourtney.

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!
