Kourtney Kardashian shares completely naked photo on Instagram

Kourtney Kardashian made jaws drop on Sunday when she shared another completely nude photo from her recent naked photo shoot in Costa Rica.

The oldest Kardashian sister posted the photo on Mother's Day -- which seemed appropriate given that she's one hot momma! The 38-year-old bombshell looked absolutely stunning in the risqué photo, leaving almost nothing to the imagination.

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.
