Ms. Kelly: Diva Deluxe (stylized as Ms. Kelly • Diva Deluxe) is the debut extended play (EP) by American singer Kelly Rowland. It was released on March 18, 2008 through Columbia Records in collaboration with Music World Entertainment and Sony BMG Music Entertainment. A digital-only collection of new songs and previously unreleased remixes, it became available exclusively through major online digital music providers. Initially planned to be included on a reissue of Rowland's second solo album, Ms. Kelly (2007), she announced that the eight tracks would be included on a standalone release. A deluxe edition of the original album, entitled Ms. Kelly Deluxe, was released on May 7, 2008.

Kelly Rowland's second solo album Ms. Kelly was released in June 2007. Not as successful as its predecessor Simply Deep (2002), the album produced the hit singles "Like This" and "Work". Originally entitled My Story, the album's first version was actually scheduled for a June 2006 release, but the singer, her management and Columbia Records decided to shelve the album at the last minute to re-work a version with a different vibe as the singer considered the final track listing "too full of midtempos and ballads." Rowland eventually consulted additional producers to collaborate on the album, renamed Ms. Kelly, including Billy Mann, Scott Storch, and Atlanta-based Polow da Don who contributed to "Like This", a collaboration with rapper Eve. A moderate success around the globe, the song reached the top-ten in Ireland and the UK, and the top-twenty in Australia and New Zealand. Upon its release, Ms. Kelly debuted at number six on the Billboard 200, and number two on the Top R&B/Hip-Hop Albums chart, with moderately successful first week sales of 86,000 copies. Outside the US, the album widely failed to reprise the success of Simply Deep, barely reaching the top-forty on the majority of all charts it appeared on, except for the UK, where it opened at number 37.
