The Pussycat Dolls were launched into mainstream recognition following the release of "PCD", which contained the number-one singles "Don't Cha", "Buttons" and "Stickwitu". Roberts sang co-lead with Bachar and Sutta in the "Stickwitu" single B-side, "Santa Baby". Bachar's departure from the group preceded the release of their second and final studio album, "Doll Domination", which contains hit singles, "When I Grow Up", "I Hate This Part" and "Jai Ho! (You Are My Destiny)". Roberts recorded a solo song called "Played" for the "Doll Domination"'s deluxe edition.
