Katy Perry launched her Prismatic world tour at Odyssey Arena in Belfast, Northern Island Wednesday (May 7), delivering the sold-out audience a spectacle of costumes and colors. 

The pop diva’s outfit changes included a “Cats”-like leotard ("Cat-oure") in pink and a Cleopatra ensemble. 

Perry served fans a spoiler on Instagram earlier in the day, posting the tour set list:

One surprise was a mashup of her “International Smile” with Madonna’s “Vogue” midway through the set. She otherwise performed the majority of “Prism” and her hits going all the way back to “Kissed a Girl”.
