‘Keeping up with the Kardashians’ Spoilers: Kim Claims She ‘Bought’ Older Sister’s Career

Fans of the reality TV show, "Keeping up with the Kardashians," can expect a lot of drama on this Sunday's episode.

In a clip, which was obtained by PEOPLE, Kim asks older sister Kourtney to appear in her mobile game app, "Kim Kardashian: Hollywood." The app is highly successful and made $74 million last year according to AdWeek.

Kourtney states that she does not to be a part of the app, which is a decision that she has changed since the episode was taped. Kim finds Kourtney's response very unexpected since she has "done so much" for older sister.

"It's ridiculous for you to just not do that for me as a favor, because I've done so much for you," Kim said.

Kim continues by telling Kourtney that Scott Disick, Kourtney's long-term beau and father of her three children, told her to bribe Kourtney with a pair of shoes.

Kim said, "And for Scott 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 sh- I've done for her?' I said to Scott, 'I'm not buying her a f-king pair of shoes - I bought her a f-king career!'"

Throughout the exchange, the youngest of the three, Khloe, stayed quiet for once.

The clip ends right before Kourtney can respond to Kim. But Kourtney sure looks annoyed.

In another sneak peak of this week's episode, Kim asks Kourtney and Khloe whether or not they want to be in her app. She says that their youngest two half-sisters, Kendall and Kylie Jenner have already stated that they want to be apart of it. Kourtney, however, has some concerns about why they can use her name but not pay her.

In the solo confessional part of the show, Kourtney, who was pregnant at the time, said, "Kim's making it seem like she's doing us a favor by having us in her video game."

In Kim's confessional, she stated, "Kourtney is always difficult. When we were first starting out our careers, I always helped them out ... She should do this for me, with no questions asked."
