The oldest sibling in the Kardashian-Jenner clan, Kourtney Kardashian, has often been known as the tough-love sister. Mom to three, health nut, workout advocate, and clean freak, the eldest sister is also funny, cool, and definitely a blast to hang out with (or so I would like to imagine).
However, she may also be the Kardashian selfie queen, giving Kim a run for her money when it comes to posting the self-posed shots. And while it may be common knowledge that Kourt is pretty stunning, we're pretty sure these photos may make this beauty (who seemingly doesn't age!) the sexiest sister of them all.
Catch up with all of Kourtney's sexy self-portraits so far this year, but we're pretty sure that the best is still yet to come.
