Katy Perry hit the red carpet at the 2014 Grammy Awards in a Valentino dress with musical notes on it, but shortly after this she completely changed her look when she took the stage to perform her latest single "Dark Horse." From the hair to the outfit to the fact that she was surrounded by flames, it was quite a switch!

Katy is nominated for Song of the Year for �Roar� and Best Pop Solo Performance for �Roar,� and though she's been nominated for eleven Grammy awards over the years, she still hasn't won one!

Maybe this will be her lucky break?
