Kim Kardashian Flaunts Bikini Body Beside Very Pregnant Kourtney

Kim Kardashian bared her enviable curves on the beaches of Mexico on a recent vacation with her sister Kourtney an nephew Mason.

The bodacious brunette wasn't content with just lounging around all day, so she tried her hand at body boarding in the warm ocean. Kim looked to be having the time of her life splashing around in the water, sporting a big smile on her face the whole time.

Kim's sister Kourtney didn't let her burgeoning baby bump get in the way of celebrating her 33rd birthday, as she played around with her son Mason on the beach. She's due to give birth in June.
