Watch Ke$ha Rock in Rio

Ke$ha has never exactly been one to make demure, commonplace fashion choices, but she may have outdone herself arriving in Rio de Janeiro wearing a plush hammerhead shark strapped to her face as a mask. (Suddenly Katy Perry’s Carmen Miranda mask doesn’t seem odd at all!) The backstabbing songstress was in town to play Rock In Rio, and rock it she did, performing hits from Animal and Cannibal including “Tik Tok,” “F*ck Him (He’s A DJ),” “Blah Blah Blah,” and “Blow.” If you currently have a stuffed shark obstructing your vision, we suggest you remove it before watching below.
