Katy Perry has been a lot of things throughout the promotion of Prism. She's been a geisha, a goth, an Amazon, a significant other, a superhuman, and now she's Cleopatra or the magical, wrathful queen known as Katypatra. Even though at the GRAMMYs, she played a witch in her performance.
As she say in the song, you don't want to make her your enemy.
With Katy, it's less about memes and more about over the top costumes from hieroglyphic wigs, bejeweled grillz and goldplated minis.
