Witness: The Tour has Perry booked through 2017 and most of 2018 , too. The new season of American Idol is set to premiere on ABC sometime in 2018, though the network hasn't set a clear date yet. Perry does have a break from Witness in April, though. Here's hoping that the stars align and she can get a break from what looks to be a grueling schedule. But if she follows her own advice and manages to stay uncoupled, it should be no sweat at all.
