She released her debut album Chain Letter in March 2005. It sold 340,000 copies in the United States. The album features her hit debut single, "Girlfight" released late 2004, in a collaboration with rappers Big Boi and Lil Jon, a song about tension between two girls which ends up in a catfight.
The first single from her second album Physical Education was "D-Girl" ("Dope Girl"), which did not chart, along with a second single, "Pimped Out", in November 2006. The release of the album was canceled during the Capitol & Virgin Records merge in 2007, the future of the project is currently unknown, but this seems to be scrapped and unreleased due to work on her third studio album. Valentine has been in the studio working on her next album, due out in 2009.
