Brandy cut her Chicago performance short during The Boy Is Mine Tour Saturday night (October 18) due to a sudden health scare that forced her offstage before the show’s signature duet.

The R&B star left the crowd stunned when she exited the stage before performing “The Boy Is Mine” with Monica, their chart-topping 1998 hit that spent 13 weeks at No. 1 on the Billboard Hot 100. The abrupt departure came without warning, leaving concertgoers confused and concerned. Brandy addressed the incident in a statement posted to social media, revealing that a medical issue led to her early exit.

The tour, which brings together two of the most celebrated voices in Hip-Hop and R&B;, continues through December 14. The pair’s reunion on stage has been a nostalgic draw for longtime listeners, especially those who remember the original release of “The Boy Is Mine” during the late ’90s. Brandy’s health update comes amid a demanding tour schedule packed with rehearsals and back-to-back performances. Health-related exits mid-show are rare for the seasoned performer, making Saturday’s moment all the more concerning for those in attendance.
