Kardashian's picture is presumably from her infamous naked photo shoot that she had during her family's vacation to Costa Rica earlier this year. The sexy shoot, which aired during Sunday night's episode of "Keeping Up With the Kardashians," featured the mother of three getting wet and wild in the pool and surrounding greenery at the family's epic rental.

She had previously shared another pic from the aforementioned shoot, which showed her flipping her hair in dramatic fashion in the pool.
