Who’s That Girl

"Who's That Girl" is a song by American singer-songwriter Madonna from the soundtrack album 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".
Featuring instrumentation from drums, bass, and stringed instruments, "Who's That Girl" continued Madonna's fascination with Hispanic culture by incorporating Spanish lyrics and using the effect of double vocals. Although it received mixed reactions from reviewers, the song became Madonna's sixth single to top the Billboard Hot 100, while peaking atop the charts in countries like the United Kingdom, Canada, Netherlands, Ireland and Belgium. It was also nominated for "Best Song From A Motion Picture" at the 1988 Grammy Awards and "Best Original Song" at the 1988 Golden Globe Awards.
The music video portrayed a different persona of Madonna, rather than her film character for which it was released. Like the song, it incorporated Hispanic culture and portrayed her dressed in Spanish style as a young lady in search of a treasure. Madonna performed the song once on the Who's That Girl World Tour in 1987. The song has been covered by many artists and has appeared in compilations and tribute albums.
