"What a Girl Wants" is a song by American singer Christina Aguilera, taken from her debut album Christina Aguilera (1999). A re-recorded version was released on November 28, 1999 by RCA Records as the album's second single, following the commercial success of the album's lead single "Genie in a Bottle". The song was written by Shelly Peiken and Guy Roche. The song was completed and pitched to RCA executive Ron Fair as "What a Girl Needs" and was renamed "What a Girl Wants"; Fair later gave the track to Aguilera. A Spanish version of the song, titled "Una Mujer," was included on Aguilera's second studio album Mi Reflejo (2000).
