Best: Jennifer Lopez and Iggy Azalea Bring Up the Rear
With the emergence of Iggy Azalea in 2014, one had to wonder: Would her AMA performance with Jennifer Lopez be the moment the booty baton was passed? In short, no. Because while Lopez, who at this point is sort of the Rock Raines of Rump (hey, they both relied heavily on their backsides), certainly played nice with Iggy, it was clear that this was her performance. She got to hit all the contortionist high spots, and was the beneficiary of the best production moments. When she and Azalea did share the stage, it was still clear who was in charge. Then, just to further cement her status, Lopez closed the show solo, strutting and shaking her way across the stage before backing it up to Pitbull to send the show home.
