Count Kendall Jenner as one celebrity who won't waste an ounce of sunny weather! The model let loose with a pal in Malibu, CA, on Wednesday, donning a white tube top and tiny blue bikini bottom. With a matching Frisbee in hand, Kendall once again showed us she inherited her dad Bruce Jenner's athletic genes. The reality-star-turned-high-fashion-regular has flaunted her svelte physique quite a few times since she turned 18 in November. Most recently, Kendall got in on Calvin Klein's star-studded "show yours. #mycalvins" campaign [1], and we'll never forget her revealing trip down the runway [2] in a completely sheer Marc Jacobs shirt, giving her older siblings a run for their money in the wardrobe department. Which of the sisters would be your BFF? Take our Kardashian-Jenner quiz [3] to find out, and keep scrolling to see Kendall's happy beach day!
