Katy Perry indulged in all manner of teenage dreams during her co-hosting gig last night at the Teen Choice Awards in Los Angeles. The "California Gurls" singer shared hosting duties with the male cast-members of Glee, using the show as an opportunity to go back to school.
Perry dressed up as a cheerleader, a prom queen, a goth, a hippie and a mouth-gear-wearing nerd. Perry ably handled hosting duties (and costume changes), as celebs like Sandra Bullock, Taylor Lautner, Robert Pattinson and Megan Fox all took home awards.
