Kendall Jenner Tells Kim Kardashian She's Pregnant, And It's Hilarious (Video)

What are sisters for if not for pranking? On Wednesday's premiere of "Kocktails with Khloé," Kendall Jenner prank called Kim K to tell her she was pregnant.

With Khloé Kardashian, Brandi Glanville, Aisha Tyler and Kym Whitley listening in, Kim gave the best advice for expecting mothers:

Today is not the day. I'm on, like, one hour of sleep... I wanna, like, die.

When Kendall begins to fake tears, Kim asks if she wants her to come over with her "30 kids" so she can experience it for herself. Way to go, Kim, for telling it like it is.

Watch the full clip of the hilarity below, and make sure to tune into "Kocktails with Khloé" Wednesdays at 10 pm on FYI.
