We will all agree that she looks lovely in a black bikini, but Kourtney looks amazing no matter what she is wearing on.
With her sister Kim and Chloe, Kourtney was involved in the American reality show. She is less famous comparing with her sisters, she is married and got one child.
Maybe she is not as famous as her sisters, but judging by the pictures we can conclude that she is the sexiest among them. Her sister Kim recorded a number of sexy photo sessions and became famous with her home made video without censorship. Yet, her sexy photo sessions can not be compared with those of the sexiest sister-Kourtney Kardashian.
