The entire clip is narrated by Khloe, who is dressed as her mom, Kris Jenner.
Reading from the "Great Book of Kardashian-Jenner Tales," Khloe says in the voice over, "Once upon a time, there lived a powerful queen who gave birth to five princesses, each with their own gifts and passions, from health to beauty to humor."
She continues, "But as their kingdom grew stronger, so, too, did the burdens that came with it. Oh, you want to know what happens? Well, honey, you've got to stay tuned."
The wild preview also teases Kylie and Kendall's Kylie Cosmetics collaboration, Khloe learning about her BFF Malika Haqq's pregnancy, and more.
