"React" is a song recorded by American girl group The Pussycat Dolls and was released by Access Records on February 7, 2020. It is the group's first song in over a decade, the last being 2009's "Hush Hush; Hush Hush", and is their first independent release since partnering with First Access Entertainment. "React" sees the return of Carmit Bachar who left the group before the release of their last album, Doll Domination (2008), although it does not feature Melody Thornton, who opted out of the reunion citing the desire to continue with her own solo music career. It was written by group member Nicole Scherzinger, along with Georgia Buchanan, Johan Gustafsson, William Simister, and Hannah Wilson. It was produced by Gustafson, Will Simms, and Swedish producer Ivares.
