Singers Brandy and Monica said their upcoming "Boy is Mine Tour" was 27 years in the making when they stopped by "Tonight" on Wednesday. The tour kicks off Oct. 16 in Cincinnati, Ohio.

Brandy and Monica are giving fans the ultimate 90s throwback. Twenty-five years after the topping the charts with their hit duet, "The Boy Is Mine," the two Grammy-winning R&B stars will close out 2025 with their first-ever co-headlining tour this fall.

The tour marks a historic reunion for the duo whose 1998 duet spent a record-breaking 13 consecutive weeks at No. 1 on the Billboard Hot 100, placing them alongside Whitney Houston and Mariah Carey as artists who have commanded the chart's top spot for 13 weeks or more.
