Dude Katy Perry is done.. I don't care what any of her stupid ass KATY KATS stans have to say. Chained to the Rhythm flopped my tits off and Hey Hey Hey is the ONLY chance of Witness ERA to last. Ever since Dr. Luke became a public pedophile her career's over. #SORRYKATYBRATS #AKALearnFromtheQUEEN!!!!!!!
