Katy Perry celebrates Super Bowl with tattoo

During the show, she seemed to smoothly make four wardrobe changes, wearing outfits designed by Los Angeles-based Jeremy Scott of Moschino, starting with a flame-emblazoned minidress and ending with a star-spangled column gown.

Twitter got excited over what she wore to accompany that gown: What seemed to be a Wii attached to her microphone was strapped to her wrist as she floated above the stadium. [The Verge]
