Katy Perry is a girl who likes her pop upbeat and her costume changes awesome (and kind of crazy). This is her Prismatic World Tour, themed around old school Egyptian meets futuristic neon warriors…and cats. See, crazy. So, whether you wanna live the teenage dream or act like a dark horse, Katy is here to entertain to the max with her refreshingly tongue-in-cheek style. Under 15s must be accompanied by an adult.
