High Quality Content by WIKIPEDIA articles! "Who`s That Girl" is a song by American singer-songwriter Madonna from the soundtrack album Who`s That Girl of the motion picture of same name. It was released on June 30, 1987, by Sire Records as the first single from the album. It later appeared on the 1991 UK compilation EP The Holiday Collection, which was released to accompany the 1990 compilation album The Immaculate Collection, and has since been included on the two-disc edition of her 2009 greatest hits album Celebration. While shooting for the film, then called Slammer, Madonna had requested Patrick Leonard to develop an uptempo song that captured the nature of her film persona. She later added the lyrics and vocals to the demo tape developed by Leonard, and decided to call both the song and the movie "Who`s That Girl".
