Katy Perry has rescheduled the Philadelphia stop on her "Witness" tour due to production delays, the singer announced this week.
Initially scheduled to hit Philadelphia on Sept. 18, Perry's "Witness" tour will now come to town on Oct. 12 at the Wells Fargo Center. All tickets purchased for the original show will be honored on the rescheduled date, according to a release.
The tour is now scheduled to kick off on Sept. 19 in Montreal.
Perry indicated that "major elements" of the tour stage design were late to arrive for her rehearsal period, and that she would be "spending the next few weeks to properly prepare the show" for fans. Additionally, Perry has added Noah Cyrus as the tour's opening act.
"I'm sorry for any inconvenience this causes, but hope everyone who sees the show will agree it was worth the wait," Perry said.
The tour will support Perry's recently released album, Witness. Singles from that release include "Bon Appétit" with Migos and "Chained to the Rhythm" with Skip Marley.
The "Witness" tour will serve as Perry's first large-scale outing since her "Prismatic" tour wrapped in 2015. However, the singer has performed a couple of Philly shows since then, including an event in support of Hillary Clinton's presidential campaign in November 2016, as well as the Democratic National Convention in July 2016.
