The Pussycat Dolls are an American pop and R&B girl group, best known for their dance-oriented music, strong vocal harmonies, and provocative image. Formed in 1995 as a burlesque troupe, they transitioned into music under the guidance of choreographer Robin Antin and music producer Jimmy Iovine. The group, featuring prominent lead vocalist Nicole Scherzinger, gained international fame with hits such as "Don't Cha" and "Buttons". Their combination of pop music with elements of hip-hop and dance has had a significant impact on the late 2000s pop scene.
