Yvette Marie Stevens (born March 23, 1953), better known by her stage name Chaka Khan ( SHAH-kə KAHN), is an American singer.

Her debut solo album featured the number-one R&B hit "I'm Every Woman" (which became a pop hit for Whitney Houston). Khan scored another R&B charts hit with "What Cha' Gonna Do for Me" before becoming the first R&B artist to have a crossover hit featuring a rapper, with her 1984 cover of Prince's "I Feel for You". More of Khan's hits include "Through the Fire" and a 1986 collaboration with Steve Winwood that produced a number-one hit on the Billboard Hot 100, "Higher Love".
