Katy Perry has once again surprised school students by rocking up unannounced -- but this time it was at her old high school!
Dressed in a sexy cheerleader outfit, Katy made a surprise appearance (though rumours had been leaked prior to the event) at Dos Pueblos High School near Santa Barbara, California, where she grew up.
The homecoming event was a show held in the football field, and Perry ran out from the stands in a blue and white cheerleader's uniform before stripping off to reveal a sexy figure-hugging halter neck dress.
Katy performed a couple of her hits, including one she dedicated to a former schoolmate who happened to be in the crowd!
After spotting him in the crowd, she said: "You were the most popular kid in my class but you never wanted to date me... You really chose right honey! What's up? What's up now?!" (Geez Katy, too big for your boots?)
Katy then dedicated her performance of the quirky song 'UR So Gay' to the embarrassed guy! Ouch!
