Katy Perry (pictured) sported a new pixie cut at the iHeartRadio Music Awards in California on Sunday, just days after she and actor Orlando Bloom announced they were "taking respectful, loving space" from each other. Perry, who used to wear a long bob, dated Bloom, 40, for more than a year. In 2012, John Mayer also cut off his curly locks after splitting from Perry, 32, according to reports.
