According to witnesses, Brandy was having audio issues and told the audience, “Give me one second y’all I gotta get my…”

Brandy left and didn’t come back, leaving Monica to finish the show alone without doing their big hit “The Boy Is Mine.”

One fan posted on X, “Wait, what? We’re all in shock. How come Brandy left the stage halfway through the #theboyisminetour? No one knows what happened, but Monica had to close the concert alone, and they didn’t sing ‘The Boy is Mine.’ She was [also] having audio problems.”

On Sunday, Brandy wrote on social media that she experienced dehydration during the show.

Brandy posted on IG, “To my dear fans in Chicago, Thank you all for the overwhelming love, support, and—most importantly—your prayers. I sincerely apologize for the abrupt end to last night’s performance in Chicago. After weeks of nonstop rehearsals, last night I experienced dehydration and feelings of wanting to faint, everyone involved agreed that prioritizing my well-being was of the utmost importance.”
