Los Angeles: Reality TV star Kourtney Kardashian recently showed off her toned body while lounging in a pool. The mother of three, 37, donned a skimpy black string bikini for the afternoon, reports usmagazine.com. “When you can't find me…” she captioned one shot, in which she looks seductively over her shoulder as she lies on her stomach atop an inflatable swan. Behind her, several lounge chairs can be seen, along with a tiny child-size fold-up chair. The two other photographs show the "Keeping Up With the Kardashians" star similarly relaxing in the pool and gazing at the camera from behind oversize mirror sunglasses.
