Katy Perry is awesome.
The pop powerhouse is currently hard at work on her California Dreams tour, and last night across the pond in London, Katy was out late for a good cause.
First, she performed at the Hammersmith Apollo to rave reviews while donating some of her proceeds to Red Cross relief in Japan.
Most singers might call it a night after that, but not Katy. She then headed to the Radio 1 studios at 1 a.m. to be on the air for yet another charitable cause...
