The Pussycat Dolls (abbreviated to PCD) are an American pop girl group and dance ensemble founded by choreographer Robin Antin in 1995 as a burlesque troupe based in Los Angeles, California. After attracting national attention, Antin eventually negotiated a record deal with Interscope Records in 2003 turning the group into a music franchise. Nicole Scherzinger and Melody Thornton were introduced to strengthen the group's vocals. Since then the group has developed a global image and commercial brand overseen by Antin, Interscope and various partners. They have diversified into reality television programmes, a Las Vegas and product endorsements amongst other things.

Success as a music group came in 2005 with their first album PCD which debuted at number five in the US producing three successful singles "Don't Cha", "Buttons", and "Stickwitu"; the latter earned the group a Grammy Award nomination. Following the departure of Carmit Bachar in March 2008, the group continued as a quintet and in September of that year they released their second album, Doll Domination spawning singles "When I Grow Up", "Whatcha Think About That", "I Hate This Part", "Jai Ho! (You Are My Destiny)", "Bottle Pop" and "Hush Hush; Hush Hush".

Throughout their rise to fame, the group has been criticized for its overtly sexual image and explicit dance routines as well as for the over-emphasis on lead singer Scherzinger, who is made to sing all of the group's lead and background vocals. Despite numerous break-up rumours the group is currently taking a hiatus and will return in 2010 with their third studio album, a brand new line-up and a tour.
