Don’t worry, folks. Kendall Jenner won’t be ruining her flawless supermodel body yet any time soon!

The reality TV star appeared on her big sister’s new show, Kocktails With Khloe, where they decided to play a huge prank on their sis, Kim Kardashian. Kendall called the mother of two to reveal to her that she is pregnant.
