It was Interscope Records' Jimmy Iovine's idea to make the Pussycat Dolls version of this song. This version was released separately as a single.
Gulzar had originally written this song for the film "Yuvvraaj" (2008). The director of "Yuvvraaj" (2008), Subhash Ghai, had thought that the song's lyrics were too refined for the film and asked him to write another song instead. A.R. Rahman had then sought Ghai's permission to use the song in this film. When Ghai agreed, Gulzar made a few changes to the lyrics and Rahman then recorded it.[1][2]
