Kourtney Kardashian pics of her stripped down to her bikini, that is. She and sister Kim Kardashian frolicked in the water as the paparazzi snapped away. Though it was a little cloudy that day, the two still enjoyed their day at the beach. Notice that Kim is noticeably more pale than her sister. I don't think that either of them go tanning, so Kourtney's tan is likely natural. Kim's bathing suit was leopard print with streaks of blue. Kourtney's bikini was a true 2-piece zebra print. I just gotta say that she has a nice booty. And again, look at that cute smile in these Kourtney Kardashian pics.
