Katy Perry kicked off her 51-date North American WITNESS: The Tour at Montreal’s Bell Centre on Tuesday (September 19) and Celeb Secrets has some photos from the big night!

WITNESS: The Tour is an imaginative trip from outer-space to inner-space, from the planets to the bottom of our oceans, and a musical journey through Katy Perry’s biggest milestones and mega-hits right up to her latest album. The dramatically original staging means that there isn’t a bad seat in the house, when Katy brings out her band and dancers, along with all the bells and whistles.

Produced by AEG Presents, the tour includes two New York City shows – October 2 at Madison Square Garden and October 11 at Barclays Center – plus an evening at STAPLES Center in Los Angeles on November 7 and a December 20 concert at American Airlines Arena in Miami. The tour will resume on January 5, 2018 at Smoothie King Center in New Orleans.

Fans can catch Noah Cyrus performing ahead of Perry through November 1, followed by Purity Ring November 7 – December 20 and Carly Rae Jepsen January 5 – February 5.
