Brandy walked off the stage Saturday during the Chicago stop of “The Boy is Mine” tour due to health issues.

In videos shared on social media, Brandy told the crowd at the United Center that she needed a minute offstage, but never returned to sing as part of her co-headlining tour with fellow R&B singer Monica.

On Sunday, the “Have You Ever” singer revealed she was suffering from dehydration and fatigue on stage, and apologized for ending the show so suddenly.

“To my dear fans in Chicago, thank you for the overwhelming love, support, and – most importantly – your prayers,” she shared on social media.

“I still made the decision to try and return and give it my all despite not feeling OK. With having to make some adjustments and the show being very technical, unfortunately, it was impossible to fully connect ionically with the production.”
