However, the Sunday night event held in England did not feature an appearance by Usher.
The “No Limit” singer explained his absence via an Instagram message posted on Monday.
“So happy to see that last night’s concert in Manchester proved that love always prevails,” wrote Usher. “I would have loved to be there but It was my son’s first day at Camp Kudzu, one of the few summer camps for kids living with diabetes. This was an important day for him and for myself as a proud father. Stay strong UK.”
Grande, Pharrell Williams, Mac Miller, Black Eyed Peas, Justin Bieber, Miley Cyrus, and Katy Perry were among the acts that took to the stage for performances.
