Year: 1998

Brandy and Monica denied that "The Boy Is Mine" represented a rivalry between them, but the tabloids suggested otherwise. Monica was supposedly mad that Brandy performed it solo on The Tonight Show with Jay Leno and Brandy was reportedly upset that Monica chose to use the name of the duet for the title of her second album. Eventually, it culminated in a VMA performance—with the two looking like our fantasy prom dates—that was meant to squash the rumored beef.

However, earlier this year, Monica confirmed to Angie Martinez on Hot97 that there was a physical altercation between the two before they hit the stage that year.
