Katy Perry’s WITNESS: The Tour will launch nearly two weeks late due to production delays. The tour, which was originally scheduled to begin Sept. 7 in Columbus, Ohio, will now kick off on September 19 at Montreal’s Bell Centre “to accommodate the complexity of the scope and enormous scale of this tour,” according to a press release. The rescheduled dates are listed below

“Due to unavoidable production delays, major elements of my tour stage design could not be available for me to rehearse on until this week,” said Katy Perry. “I’ll be spending the next few weeks taking the time to properly prepare the show to be an experience I am proud to share with you. I’m sorry for any inconvenience this causes, but hope everyone who sees the show will agree it was worth the wait. My first show on WITNESS: The Tour will be in Montreal on September 19.” The North American arena tour is produced by AEG Presents.


Katy Perry has also revealed the tour’s opening acts. Noah Cyrus will join WITNESS: The Tour on September 19 – November 1, followed by Purity Ring on November 7 – December 20 and Carly Rae Jepsen on January 5 – February 5.

All tickets purchased for the original concert dates will be honored for the new date, refunds available at point of purchase.

Perry will host MTV’s Video Music Awards on Aug. 27.
