Kourtney Kardashian and Kris Jenner are currently closing out their Summer with a stunning European vacation [1], and their latest stop in Antibes, France, might be their most adventurous yet. Kourtney, who brought along her adorable kids [2] for the fun getaway, showed off her amazing body on Instagram [3] last week when the family was in Italy, but her more recent swimsuit is definitely the standout. While soaking up the sun on a luxurious yacht on Wednesday, she rocked a black one-piece that read "Khlo $$$$$," an obvious reference to her sister Khloé's nickname. In addition to showing her sibling some love from halfway across the world, Kourtney also showed off her wild side when she had fun on the yacht's water slide. While she flew into the water pretty seamlessly, mom Kris had a bit more trouble. But, as they've proven time and time again, no situation can ever really keep them down, and they seemed to shake it off like pros.
