Brandy leaves the stage in the middle of a concert, Monica ends up alone

Brandy And Monique‘s The Boy Is Mine tour hit a snag Saturday night when Brandy abruptly left the stage in the middle of the performance, leaving Monica to close the show solo.

The R&B legends were performing at Chicago’s United Center when Brandy appeared frustrated by sound issues and stopped mid-song.

“Give me a second, I need to get my…” she told the crowd before walking backstage.

But Brandy never returned and after several minutes of confusion, Monica continued alone and ended the evening without performing their 1998 duet, “The Boy Is Mine.”

Fans flooded social media with clips and questions, wondering why the series ended early. Saturday’s hiccups come just months after the couple announced their reunion tour marking more than two decades since their hit single made music history and years after their highly publicized feud.
