On March 3 , 2008 Carmit Bachar announced via the group 's website had left the group intending to pursue a solo career . At the time of her departure , she had been the longest member of the group , joining in 1995 when they were a burlesque act . Several days later , they performed for the first time without Bachar for the Operation MySpace concert which honored US troops stationed in Kuwait . In May 2008 , they released their second album 's lead single " When I Grow Up " , which reached the top ten in 16 countries . At the 2008 MTV Video Music Awards , its accompanying music video was nominated for six awards , the most of that ceremony , and went on to win Best Dancing in a Video . '' Doll Domination '' was released in September 2008 to mixed reviews . It attained their highest peak position on the '' Billboard '' 200 , but failed to match the sales of its predecessor , selling less than a sixth as many as '' PCD '' sold ( in the UK ) , and regarding it as a commercial disappointment . Three subsequent singles were released in 2008 , " Whatcha Think About That " , " Out of This Club " , and " I Hate This Part " ; the last one peaked at number 11 on the '' Billboard '' Hot 100 chart
