Katy Perry has proven in the past that she's a master of disguise (ie: Kathy Beth Terry) but her upcoming 'Birthday' video takes it to a whole new level! In the teaser (below) Perry portrays a whole cast of characters including Goldie the Dancer, Yosef Shulem the MC and Kriss the Clown acting as the "World's Worst Birthday Party Entertainers."

The video will officially drop on April 24th but for now, this teaser will surely hold you over.
