The Pussycat Dolls were an American girl group and dance ensemble, founded in Los Angeles, California, by choreographer Robin Antin in 1995 as a burlesque troupe. At the suggestion of Jimmy Iovine, Antin decided to take the burlesque troupe mainstream as a pop group. Antin negotiated a record deal with Interscope Geffen A&M Records in 2003 turning the group into a music franchise comprising Nicole Scherzinger, Carmit Bachar, Ashley Roberts, Jessica Sutta, Melody Thornton, and Kimberly Wyatt. Their debut single, "Sway", was featured on the soundtrack of the 2004 film Shall We Dance?.

A girl group is a music act featuring several female singers who generally harmonize together. The term "girl group" is also used in a narrower sense in the United States to denote the wave of American female pop music singing groups, many of whom were influenced by doo-wop and which flourished in the late 1950s and early 1960s between the decline of early rock and roll and start of the British Invasion. All-female bands, in which members also play instruments, are usually considered a separate phenomenon. These groups are sometimes called "girl bands" to differentiate, although this terminology is not universally followed.
