"I'm Every Woman" is a 1978 hit single by Chaka Khan, her first hit outside of her recordings with funk band Rufus. Produced by Arif Mardin and written by successful songwriting team Nickolas Ashford and Valerie Simpson, the soul/disco song was a number one hit on the R&B singles chart, and is today Khan's signature song. Whitney Houston and her mother Cissy sang backup on this version. Houston would then cover the song in 1992, turning in into an even bigger hit.
