Nobody's Business (song)

"Nobody's Business" is a song recorded by Barbadian singer Rihanna for her seventh studio album Unapologetic (2012). Co-written by Rihanna together with its producers Terius "The-Dream" Nash and Carlos "Los" McKinney, it features guest vocals by American singer Chris Brown. It is their third collaboration following the domestic violence case that happened between them in 2009. "Nobody's Business" is a house, disco-pop and R&B-funk song that mixes Chicago stepping and features strings, piano, and a four-on-the-floor kick drum. It contains interpolation of the 1987 single "The Way You Make Me Feel" by Michael Jackson.

"Nobody's Business" received generally positive reviews from contemporary music critics with many of them labeling the song as standout on the album. Despite that, some journalists criticized Rihanna's decision to collaborate with Brown again because of their former relationship and domestic violence case. Following the release of Unapologetic, as a result of the strong digital downloads, the song charted on multiple charts worldwide; it peaked at number 36 on the French Singles Chart, number seven on the UK Singles R&B Chart, number 63 on the UK Singles Chart and number 39 on the US Hot R&B/Hip-Hop Songs.
