The duo's performance of killer Artpop collabo "Do What U Want" on SNL last week was lackluster and messy, and even R. Kelly knew it ("No offense to Saturday Night Live but that was a dress rehearsal for AMAs," he told Rolling Stone on the red carpet). But the pair brought a hilariously over-the-top bit set in the oval office to the AMAs that smacked of Kelly's beloved hip-hopera "Trapped in the Closet." Kelly was smooth, Gaga was on point, and though the performance strayed a bit from its original concept toward the end (Gaga plastered the set with self-deprecating headlines), it was one of the night's strongest performances.
