Reality star,  Kim Kardashian, who is currently on holiday with her family in Costa Rica showcased her killer curves as she stepped out on to the beach.

The 38-year-old mother of four put her curvy backside in a two-piece bikini as she went for a quick dip in the ocean.

Kim who brought her daughter North along was also joined by her older sister Kourtney Kardashian, 40, and her ex-Scott Disick, with their 3 children.

At one point, the trio were pictured resting on loungers by the shore while their kids played nearby. Scott’s girlfriend, Sophia Richie, wasn’t on the trip.
