Kris Jenner reveals her favourite daughter, the easiest to work with & the most difficult

Are parents really supposed to declare their favourite child openly?

Kris Jenner shared a lot of background during Thursday's Keeping Up With The Kardashians reunion on E! And at one point the momager revealed who was the easiest to work with on the show. 

Kim, 40, has long been her favorite as Kris has said that is her 'go to' when she has an issue, but she did not land on top. 

Kris said Kendall was the easiest to work with. The star is a supermodel who has landed on the cover of Vogue and is the star of Versace and Calvin Klein campaigns. 

The momager revealed that of all her brood, Kourtney Kardashian was the most difficult and gave her 'the most lip,' in conversation with Andy Cohen.

Do you know your mum's favourite child, TOYsters?
