Aug. 31 (UPI) -- Brandy and Monica will be facing off in a Verzuz battle on Monday at 8 p.m. EDT on Apple Music on Instagram.
"It's almost time......," Monica said on Instagram next to a hoodie fans can purchase from the Verzuz store. T-shirts are also available with all proceeds being donated to non-profit organization When We All Vote.
Brandy and Monica have a history together after appearing in 1998's "The Boy Is Mine," a track where the singers argue over a shared lover.
The song led to speculation that Monica and Brandy were feuding which then led to friction between the pair.
"It was not something that I would say was anyone's fault," Monica said in an interview with Entertainment Tonight.
"We all added to it and after a while it became real," she continued.
