Kim Kardashian West has blasted Kris Jenner for making Kourtney Kardashian the executor of her will.

The 59-year-old matriarch's decision to put her eldest daughter in charge of her will following her divorce from Bruce Jenner has left the 34-year-old television personality fuming.

In a clip from an upcoming episode of 'Keeping Up With The Kardashians', Kris breaks the news to Bruce and Kim, telling them: ''Kourtney is the executor of the estate and the decision-maker for my life.''

To which Kim immediately replies to say: ''That's heavy stuff. Kourtney is the most indecisive person on the planet.''

The 65-year-old former Olympian sides with his step daughter, telling his ex-wife: ''She's can't even decide on what wallpaper she wants in her house. I should be the one to make the decision.''

In fact, Kim believes she should be given the role as the executor as she is the most ''levelheaded''.

She told Kris: ''[Kourtney] is really stubborn, she can't make a decision, and she's just not as smart as I thought she was [when we were] growing up. I truly think I am the most levelheaded.''

Following their chat in the kitchen, Kris then tells the cameras she may have changed her mind.

She said: ''The person that I choose for this responsibility has to be able to make a great judgement really fast so now I'm thinking Kourtney might be the wrong choice because she's going to be the most indecisive.''
