Like her momager Kris Jenner, Kim Kardashian West definitely loves her friends.

The reality star owes longtime BFF Jonathan Cheban a solid after he did some of her dirty work during her pregnancy with son Saint, now 1 month old.

In a sneak peek at this week’s episode of Keeping Up with the Kardashians, Kardashian and her assistant are too busy launching her app/website to make an important stop at her OB-GYN’s lab – so the task falls to the Dishh founder.

“I need to pee in a cup and I just need it dropped off to the doctor,” says Kardashian, 35, laughing hysterically.

“Are you f—ing sick?” cries Cheban, 41. “What do you mean, you want me to walk around with your piss?”

“No one will ever know!” a giggling Kardashian insists. “Let me just pee and I’ll conceal it and see if you even feel the warmth of the pee.”

In the end, Cheban is a total trooper, transporting his pregnant pal’s double-bagged urine sample to the proper place.
