"It All Belongs to Me" is a duet by American recording artists Monica and Brandy. Written and produced by Rico Love, Earl Hood, and Eric Goudy II, the track originally belonged to R. Kelly. He then gave the song to Monica and the label presented the song to Brandy, who expressed her wish to record a duet. After Clive Davis authorized it, they went to a recording studio located in Miami, Florida to record the track. Three different versions were made, with one being released as the official first single from Monica's seventh studio album New Life on February 10, 2012, through RCA Records. It is the first time Monica and Brandy worked together since they collaborated on "The Boy Is Mine" (1998).

Musically, "It All Belongs to Me" is a midtempo R&B ballad . Lyrically, the song is a female empowerment anthem in which both singers claims their belongings as they leave their abusive boyfriends behind. The chorus has references to MacBook and Facebook. "It All Belongs to Me" also received several comparisons to Beyoncé Knowles' single "Irreplaceable" (2006). Following the release of the single, Brandy revealed that she expected female listeners to love the song. "It All Belongs to Me" was well received by the public. However, it received mixed reviews from contemporary critics. Most critics praised both singers' vocal performance, but were disappointed with the track, commenting that the hype behind it was big, but also noting that the track wouldn't be as successful as "The Boy Is Mine". "It All Belongs to Me" has reached number 23 on Billboard's Hot R&B/Hip-Hop Songs chart.
