Katy Perry [1] shone bright at the iHeartRadio Music Awards [2] in LA on Sunday. The "Chained to the Rhythm [3]" singer stunned in a white and gold strapless jumpsuit, which paired perfectly with her new blonde pixie cut. Katy's fun outing marks her first appearance since her split from Orlando Bloom [4]. After a little over a year of dating [5], the two called it quits in late February, and the duo's reps released a joint statement [6] that said they would be "taking respectful, loving space at this time." A couple days later, Katy addressed the split via Twitter, urging "a new way of thinking" and insisting that "no one's a victim or a villain." Orlando has yet to comment on the matter, but he was spotted chatting up women on the beach [7] over the weekend.
