The Kardashian-Jenner clan is flying high during their vacation in St. Barts ? literally. Kim, Kourtney, and Khloé Kardashian, along with Kendall, Kylie, and Kris Jenner, soaked up the sun while spending the day on a luxurious yacht on Wednesday. Kim and Kourtney then took to Instagram to share adorable photos of North West and Penelope Disick talking to a "real" mermaid by the pool.
