"Lady" is the final single from the 2004 album Baptism by American rock musician Lenny Kravitz. It was released on November 23, 2004. The song is believed to be written about Kravitz's then-girlfriend, Nicole Kidman. The track was used heavily in the GAP ads. The commercials featured Kravitz dancing and singing the song with his guitar to Sarah Jessica Parker.
The video was directed by Philip Andelman. It consists of Kravitz playing guitar and singing in a circular stage, while women are dancing around him. There are lights that change depending on the intensity of the sound of the song.
