To pursue a solo career, she moved to Los Angeles, California and signed to Subliminal Entertainment/Virgin Records. She released her debut album Chain Letter in March of 2005. It sold 340,000 copies in the US. 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 second single, "Pimped Out" was released in November 2006 and went nowhere, becoming another very unsuccessful single for Valentine. The album has been delayed several times and the current release date
