Kylie Jenner woke up to a big surprise from her sister Khloé Kardashian - and her mini accomplices. "I slept over at my mom's house," Kylie, 28, shared in an Instagram video Saturday, September 13, of her Mercedes-Benz G 580 wagon covered in toilet paper and neon Silly String. "You bitch! You little bitch!" she screamed as Khloé, 41, could be seen hiding before running into the house.
