Cyrus apparently had an allergic reaction to a medication she’d recently started taking, reported Entertainment Weekly.

“Miley Cyrus’ Bangerz tour date scheduled for tonight, April 15, at Sprint Center in Kansas City has been canceled,” read a statement from the Spirit Center. “Cyrus has been hospitalized for a severe allergic reaction to antibiotics and has been placed on medical rest by her doctors. She will not be able to perform as scheduled. Refunds for tickets will be available at the point of ticket purchase. Tickets purchased online or by phone will be automatically refunded.”
