Katy Perry's 2012 GRAMMY Revenge Song
Never one to disappoint her fans, Katy Perry brought the thunder as she took the stage at the 54th Annual Grammy Awards last night (February 12).
Prior to the performance, a Perry pal told press, "Katy has a huge surprise in store and everyone is going to be talking about it. It’s going to be totally epic. She can’t wait for Sunday and everyone is so excited for her to show that the split hasn’t taken away her spirit and it’s only made her stronger.”
