Jennifer Lopez and Iggy Azalea rub butts in ‘Booty’ music video

“Prepare the audience for maximum impact,” Jennifer Lopez warns in the opening, eternal seconds of her “Booty” video with Iggy Azalea.

But how quickly could we forget the maximum impact of another booty-centric, twerking, girl-on-girl music video recently, Nicki Minaj's “Anaconda?”

Watch each, and below I make an analytical comparison — a booty battle if you will — of what it is to see two female superstars shake their famous derrieres.

“Booty” has an inordinate amount of dancing booties without heads or faces in the frame. This may not mean much on face (derp!) value, but the literal removal of the personal, the name to a body, is a disembodiment. The interchangeability of the women renders the bodies as objects.

I would contend there is an important distinction here: that Iggy Azalea and Jennifer Lopez are, in no way, the same person.

Watch Nicki Minaj's eye contact with the camera, and the confrontational eye contact between the dancers and her and the dancers. Lopez uses lots of eye contact with the camera, but — again — that whole no-face-all-body thing. She and Azalea have lots of contact, but not of the eye variety.
