The KarJenner prank wars have begun with a bang! On Saturday, Kylie Jenner took to TikTok to share footage of an unwelcome sight: her luxury Mercedes G-Wagon COVERED in toilet paper and silly string! OMG! Through laughter, the 28-year-old explains to followers "I slept over at my mom's house." She then pans the camera over to reveal her big sis Khloé Kardashian sneakily catching a glimpse. Kylie playfully shouts: "You bitch!" As fans may recall, Khloé and momma Kris Jenner built homes on the same property, so they ALWAYS know who's visiting each other.
