Katy Perry’s scheduled performance at Belgium’s Werchter Boutique festival is canceled after organizers cite “inclement weather” and crowd-safety concerns. Multiple outlets report that the show is called off shortly before showtime on Saturday, leaving the singer without the opportunity to take the stage.

Deadline and The Independent both describe the cancellation as being driven by extreme weather conditions affecting festival operations and attendee safety. Rolling Stone adds that Perry receives the news while backstage during hair and makeup, and she says the decision is “beyond my control,” describing it as something she is not given a choice about.

Perry issues an apology in connection with the cancellation, according to the reports, and the event is postponed or delayed without immediate details on a new date. The outlets agree that the cancellation is linked specifically to weather-related factors and the festival’s responsibility for crowd safety.
