After pushing the start of her tour in order to hammer out and fine-tune some of the production details Katy Perry finally kicked it off in Montreal.
Katy looked fierce in diva ready outfits ranging from a head-to-toe hooded, sequin latex suit to a crop top that flashed digital messages on her chest.
She tore through twenty-one of her hits starting the show with "Witness" and performing "Firework" as her encore and the crowd loved it!
