Kris Jenner dished on which of her mega-famous daughters were the 'hardest to manage' during Thursday's Keeping Up With The Kardashians reunion on E!

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.

Before she could answer the Poosh founder seemed to fess up to being less than a walk in the park when it came to matters of business, later sharing that she says 'no to most things.'

Cohen did not shy away from the hard hitting questions as he asked Kris to name the both the easiest and the toughest of her kids when it came to being a manager.

'Well, if I'm gonna be honest...,' she began before Kourtney interjected: 'I already know the hardest!' with a cheeky smile.

'I think Kendall's the easiest. She's also the kid who when she was seven would put herself to bed every night and say "I'm done for the day, Mommy. My room is clean,"' which prompted an approving look from the model.

Andy doubled down as he asked her to share who gave 'the most lip,' as Kris said 'Kourtney,' to which her eldest also concurred that it was certainly true.

'Cause I don't want to do things if it's not something I'm really into doing. My answer is, like, no to most things. And if it's gonna be yes, like, I want to know every detail of what I'm gonna be asked of,' Kourtney said.

Kris also said that she does indeed take a 10 percent cut for negotiating deals on behalf of her kids but said she doesn't 'feel guilty' because she works 'really hard.'

Kourtney had been vocal about her growing disinterest in shooting the family's hit E! show prompting many sit down conversations with sisters Kim and Khloe who felt they were unfairly pulling their weight while she wasn't.

'Now I'm filming, maybe like, two days a week because I don't want to be in a toxic environment. I just feel so much better giving my focus and attention to my kids and to Poosh and things that I'm excited about,' she had said in a confessional.

And in the vein of being less than forthcoming with her time and certain aspects of her life, Khloe called Kourtney out on the reunion for forbidding her sisters to talk about her relationship with Travis Barker on camera.

'We weren't even allowed to talk about it,' the Good American founder began. 'We're not saying to put him on, but Kourtney wouldn't even let us mention him even though there's Paparazzi photos.So we were frustrated that we couldn't even talk about what Kourtney was doing.'

But she brushed off the critique and chuckled after it was said that she got an 'unfair advantage.' 'Whatever we'd like to call it, I don't mind,' she quipped.

Things with the Blink-182 drummer continue to get serious and the pair recently splashed out on a $12M Palm Springs house with both of their names listed on the deed.

It has also been previously reported that an engagement for the pair could be 'right around the corner,' per an Us Weekly insider.
