At this point, Jen Selter really needs no introduction. Best Butt on Instagram, etc etc etc.... You know all that already.

We were just pondering how excellent a world this is where a young woman can gain more than 20 million social media followers just because she's got a great rear end. Although, maybe it's not so weird after all -- how did Kim Kardashian get so damn famous? Her ass. Before her, Jennifer Lopez's posterior was at the top (or should we say bottom?) of the booty-shaped pyramid. Speaking of pyramids, we bet this dates all the way back to Cleopatra's butt. Bet she would've had a hell of an Instagram.
