Cringe! Kim Kardashian asks her bestie Jonathan Cheban for an unusual favor on the upcoming episode of Keeping Up With the Kardashians, airing Sunday, January 10.

“So because I’ve had, you know, pregnancy issues in the past, I need something dropped off at the lab,” a pregnant Kardashian, 35, begins her request. “Can you drop one thing off for me?”

Cheban, 41, looks doubtful before his laughing BFF reveals that she needs him to bring a cup of her urine to the doctor’s office.

“Are you f--king sick?” Cheban exclaims. “What do you mean, you want me to walk around with your piss?”

The mom of two can barely keep a straight face as she reassures Cheban that “no one will ever know,” explaining that she and her assistant Stephanie are both busy preparing for the launch of her website.

The Selfish author negotiates with Cheban until he finally agrees.

“I’ll just pee in it and I’ll conceal it and see if you even feel the warmth of the pee!” she says.

Keeping Up With the Kardashians airs on E! on Sunday at 9 p.m. EST.
