Katy Perry burned one of her former classmates during a surprise performance at her old high school yesterday … calling out some dumbass who ignored her during her pre-girl-kissing years.
It all went down at Dos Pueblos High School near Santa Barbara, CA — where 25-year-old Katy claims she spotted and then singled out the “most popular kid” in her class — then rubbed in the fact that he “never wanted to date” her.
Katy then poured salt in the wound by screaming, “What’s up now?” … and followed it up by dedicating her next song to him … titiled, “You’re So Gay.”
BTW, Katy started off the show wearing a cheerleader outfit … then stripped into something more revealing.
