Miller's cancellations come a few days after Grande suspended seven of her tour dates
through June 5. "Due to the tragic events in Manchester, the Dangerous Woman
tour with Ariana Grande has been suspended until we can further assess the situation and pay our proper respects to those lost," the 23-year-old singer's team said in a statement to ET. "We ask at this time that we all continue to support the city of Manchester and all those families affected by this cowardice and senseless act of violence."
