Katy Perry has been forced to postpone her Witness tour.
The singer, 32, apologised to fans in a statement released today..
"Due to unavoidable production delays, major elements of my tour stage design could not be available for me to rehearse on until this week,” she said.
“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."
There is no confirmation on whether the delay will impact on her Australian tour dates.
