True to the song's name, the performance featured a lot of booty-shaking. Lopez, 45, kicked things off in a black and white leotard that showed off her famous assets. She was joined onstage by AMA winner Azalea, who rocked a glittery metallic leotard. As they danced, patterened lights flashed across the stage, covering them in polka dots, stripes, and diamonds.

About a minute into the track, Lopez reappeared wearing a red sequined leotard with a plunging neckline. As she strutted to center stage, she slipped on a matching red sequined blazer and broke into a choreographed routine with several backup dancers.

At one point during the routine, the American Idol judge got a call on her cellphone, which she playfully dismissed as a "booty call" before sashaying away, hips swinging. She ended the song with her back — and world-famous butt — to the audience.

Lopez and Azalea's performance was the last of the night at the AMAs, which were hosted by J.Lo's pal Pitbull, who appeared on her track "I Luh Ya Papi." Other performers included Taylor Swift, Lorde, Selena Gomez, and One Direction.
