You know Hyori was going to be first on this list right?

KARA's "Mister" anyone?

Whoa, Girl's Day? More like Booty's Day!

Oh my Bora!

Girl's Generation Hyoyeon's booty was made for dancing.

CL's booty is of the baddest female.

2NE1's Minzy is so innocent off-stage, but when she gets on-stage and shakes that thang, she is nothing to mess with.

Oh, HyunA!

All you have to know is that Kahi does yoga which means her butt is in tip top shape. The singer tweeted this and said, "My butt hurts."

Oh, and more Girl's Day.
