Brandy and Monica won Best R&B Performance by a Duo or Group with Vocals at the 1999 Grammys for “The Boy Is Mine.”
Released in 1998, the duet became one of the era’s defining R&B-pop collaborations. Its call-and-response structure presents two singers arguing over the same romantic partner, turning the song’s title into a memorable musical refrain. Rodney “Darkchild” Jerkins and his production team helped shape its polished, bass-heavy sound.
The single became a major commercial success, spending 13 weeks at No. 1 on the Billboard Hot 100. It was also the first U.S. number-one pop hit for both Brandy and Monica. Their duet won the performance category at the 41st Annual Grammy Awards in February 1999.
A frequent mix-up involves Best R&B Song, a separate songwriting category at that ceremony. Lauryn Hill won that award for “Doo Wop (That Thing),” while “The Boy Is Mine” was recognized for the vocal performance by Brandy and Monica. The song was also nominated for Record of the Year.
