Katy Perry was mobbed in London earlier today when she left the BBC Live Lounge Studio where she performed her new single "Part of Me." So many fans descended upon the blue-haired pop star that police had to be called in to help control the swooning crowd. Perry, we're happy to report, basked in the adulation for a few minutes before jetting off, taking time to say hello to fans and sign autographs.
