This is 47, people!

Jennifer Lopez singlehandedly made big booties a thing, paving the way for Kim Kardashian and a host of other enhanced starlets, so she took to Instagram today and showed off her enviable bum just to remind everyone who the queen is!

Clad in a skimpy black bodysuit, the singer flashed some serious sideboob and her perfect bubble butt while posing on a bed. Caliente!

Someone should rename her ex Casper Smart to Casper Stupid, because he cheated on this!
