Kendall Jenner meets her biggest (and craziest) fan at a meet-and-greet courtesy of Nickelodeon's "You Gotta See This!" See it go down

It's official: We now know who the mischievous Jenner sister is, and that would be Kylie Jenner.

The youngest gal teamed up with Nickelodeon's You Gotta See This! to pull an elaborate prank on big sister, Kendall Jenner. Which included a meet-and-greet complete with phony photographer and a rabid fan who thinks she's just like Kendall.

But is Kendall able to play nice when the fan asks if they can trade shoes and co-host a birthday party together?!

Watch the hilarious clip above and tune in to an all new season of Kourtney & Kim Take Miami this January to see what else these sisters get into.
