"Jai Ho! " is a song by Indian composer A. R. Rahman and American girl group The Pussycat Dolls, recorded for the re-release of the group's second studio album Doll Domination (2008) and their EP Doll Domination – The Mini Collection (2009). It was released on February 23, 2009, by Interscope Records as the fourth single from the album and is an English remake of the original Hindi song "Jai Ho" which is taken from the soundtrack to the hit film Slumdog Millionaire (2008). The remake was conceived by record executives Jimmy Iovine and Ron Fair who tasked the Dolls' lead singer Nicole Scherzinger with creating a pop record that did not deviate from the original melody. Iovine and Fair also asked a number of other writers to create interpretations of the song, including Brick & Lace, The Writing Camp and Ester Dean. The final English version of "Jai Ho" was dubbed "Jai Ho! " and is sometimes also referred to as the "RF Mix" or "Ron Fair" Remix.

The Pussycat Dolls were an American girl group and dance ensemble, founded in Los Angeles, California, by choreographer Robin Antin in 1995 as a burlesque troupe. At the suggestion of Jimmy Iovine, Antin decided to take the burlesque troupe mainstream as a pop group. Antin negotiated a record deal with Interscope Geffen A&M Records in 2003 turning the group into a music franchise comprising Nicole Scherzinger, Carmit Bachar, Ashley Roberts, Jessica Sutta, Melody Thornton, and Kimberly Wyatt. Their debut single, "Sway", was featured on the soundtrack of the 2004 film Shall We Dance?.
