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.\u201d<\/p>\n Brandy and Monica Arnold<\/strong> were in the middle of their live concert, named after their 1998 duet, when the Moesha <\/i>alum quickly walked offstage<\/a> without a word.<\/p>\n \u201cI 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,\u201d she continues in her statement. \u201cUnfortunately, it was impossible to fully connect sonically with the production, I really appreciate everyone\u2019s best efforts.\u201d<\/p>\n Brandy and Monica Abruptly End \u2018The Boy Is Mine\u2019 Concert in Chicago, Walk Offstage Mid-Song<\/a><\/p>\n Brandy adds, \u201cI\u2019m deeply grateful to my sister, Monica, for stepping up with such grace and professionalism and the entire crew for their continued care and support.

Your understanding, patience, and unwavering belief mean the world to me.\u201d<\/p>\n Brandy further noted that she looks forward to \u201creturning to the stage\u201d for her and Monica\u2019s Sunday, October 19, concert in Indianapolis.<\/p>\n Brandy and Monica, 44, kicked off their The Boy Is Mine Tour <\/i>earlier this week.
