The Pussycat Dolls is a girl group that first began as a burlesque troupe, performing at The Viper Room between 1995 and 2002. In 2003, The Pussycat Dolls rebranded. They dropped their debut single "PCD" in 2005. It featured hit singles like "Don't Cha" and "Stickwitu". Between 2006 and 2007, they headlined the PCD World Tour. In 2008 the group debuted their sophomore album "Doll Domination", which featured the major hit "Buttons". They also starred in the single season reality competition show "Pussycat Dolls Present: Girlicious" that year. In 2010, The Pussycat Dolls broke up. They reunited in 2019 with all original members except Melody Thornton. Despite announcing a tour in 2020, the group broke up in 2022, and the tour never happened. In 2026, three members, Nicole Sherzinger, Ashley Roberts, and Kimberly Wyatt, reunited as "The Pussycat Dolls" and released the single "Club Song" as a trio. The PCD Forever Tour was announced shortly thereafter.
