The star is currently on vacation with her family in St. Barts, and she has the hot bikini 'gram to prove it. Late last night the mother of three shared a sexy poolside photo (above) in which she shows off her super-toned physique. In the snap, captioned "Troop Beverly Hills," the celeb dons a two-piece suit and head wrap featuring a pattern similar to the iconic palm-tree print that is used at the Beverly Hills Hotel. Kardashian topped of her look with oversize sunnies and a gold body chain. But Kourtney isn't the only one of her sisters who has shared bikini snaps during their getaway: Yesterday, Kendall and Kylie Jenner also flaunted their tropical style in swimsuit selfies on Instagram.
