Top 10 Flattest Female Celebrity Booties

5. Kourtney Kardashian

Kourtney Kardashian is the only sister in the family that doesn’t have a juicy booty like her siblings — heck, even Rob Kardashian has a big bum! But then again, I should also stress that Rob and Kourtney’s butts are the only natural ones — at least, I would like to assume.

While her bum isn’t quite as big as Khloe’s or Kim’s, Kourtney does tend to keep it rather toned, though it hasn’t really done anything for her, in terms of making it perkier or standout a little more. Either way, if the mother-of-three loves her bum, who is to tell her she shouldn’t?
