Jennifer Lopez and Iggy Azalea kept up their valiant work of convincing Vogue that booties exist with a performance of "Booty" at the American Music Awards on Sunday night. Wearing leotards, the duo performed their song with slightly less lube and Eos product-placement than we saw in the music video. "Prepare audience for maximum impact," the screens read, before the lights came up on Lopez, who launched into a booty-centric solo dance routine before Azalea joined her onstage.
