The Pussycat Dolls became famous around the world in 2005 with their album "PCD". It reached number five on the U.S. "Billboard" 200 Chart. The album included the hit singles "Don't Cha", "Buttons", and "Stickwitu"; a song that earned the group a Grammy Award nomination. After Carmit Bachar left the group in March 2008, the group continued as a quintet. They made their second album in 2008, "Doll Domination". This album included the singles "When I Grow Up", "I Hate This Part" and "Jai Ho! (You Are My Destiny)". The group has been criticized for being too sexual in their image and dances. Some people have said they use lead singer Nicole Scherzinger too often; she sings nearly all of the group's lead and background vocals.
