It's the quote that's had us guessing for months, and now we FINALLY know who Kim Kardashian was talking about when she said she'd 'bought' someone's career.

Poor Kourtney Kardashian was on the receiving end of such words, after refusing to be a part of Kim K's mobile game.

In a new teaser for this week's episode of Keeping Up With The Kardashians, Kim is outraged as she's denied a favour.

“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.

She then relays a conversation she had with Kourtney's partner, Scott Disick, who suggested bribing Kourtney to get her own way.

“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?’” she said. “I said to Scott, ‘I’m not buying her a f–king pair of shoes – I bought her a f–king career!’”

We cannot wait to see Kourtney's response!
