The Kardashian and Jenner family jetted off to St. Barts this week for a family getaway that included Kim's daughter, North West, as well as Kourtney's kids, Mason, Penelope, and Reign. Khloé has been living it up with her sisters [1], but she also shared some fun with her nieces and nephews on Instagram. Khloé posted a sweet snap of North wearing crooked sunglasses and another making goofy faces with Mason. It looks like the vacation fun is just beginning for the group — who of course have the perfect warm-weather wardrobe [2] — so stay tuned for even more!
