We don’t condone catfights, but it sure sounded good when these two R&B princesses released this melodic duke-out about who was the better woman for their two-timing man with “The Boy is Mine” in 1998. In 2012 they came back with “It All Belongs to Me,” a follow-up song that showed the two had cleared the air about their old (fictional) flame.
On “When You Believe,” Mariah and Whitney proved that two divas could occupy the same space at the same time. And the results? Out of this world. The song, featured in the animated movie The Prince of Egypt, received a Grammy nomination for Best Pop Collaboration in 2000.
By far one of the greatest love songs of all time, Diana Ross and Lionel Richie’s vocal compatibility on “Endless Love” was just right for this ballad. The song would receive two Grammy nominations for Best Pop Vocal Performance by a Duo or Group and Record of the Year in 1982.
The self-proclaimed musical soulmates proved just how vocally connected they were on the classic “Fire and Desire.” By the end of this romantic duet, released a year after Marie made her debut, the blue-eyed soul singer unleashed some of her most memorable ad-libs in her signature soprano.
