video. Background "Who's That Chick?" was written by David Guetta, Kinda "Kee" Hamid, Patrick Leonard, Madonna, Frédéric Riesterer and Giorgio Tuinfort. The song uses a sample of Madonna's 1987 single "Who's That Girl", written by Madonna and Patrick Leonard, hence being credited as co-writers. Production of the song was helmed by Guetta, Riesterer and Tuinfort. In an interview with Akshay Bhansali for MTV News, Guetta explained that the song was originally intended for inclusion on Rihanna's fifth studio album, Loud (2010), but that he decided to include it on the re-release of his own album, One Love (2009), when it did not make Louds final cut. Guetta revealed that he was asked to produce tracks for Loud, but did not have anything which he felt would compliment Rihanna. He stated that although two artists want to collaborate and are fans of each other, it does not always come to fruition. However, after brainstorming ideas for what he could produce for the singer, Guetta came up with an idea for a song called "Who's That Chick?", and decided that it was "perfect" for Rihanna. After he completed the demo, he pre-viewed the song's instrumental on a French radio station, but did not confirm which artist would contribute vocals. Guetta played the song to Rihanna whilst backstage at one of her Last Girl on Earth (2010–2011) concerts, to which Rihanna said "Yeah, I like it." Guetta confessed that he felt as though the singer did not like it on first impressions and doubted it, but stated that after the concert, the singer told Guetta that she could not stop thinking about the song's beat whilst she performed, and asked to record it. The final cut of the song was included on One More Love (2010) and Rihanna appeared as a featured artist. Guetta concluded the interview by saying that he felt "honored" to have worked with Rihanna. Prior to the release of Loud, Rihanna clarified via Twitter that "Who's That Chick?" was not linked to Loud and that it would not appear on the album.
