Betty Davis (née Mabry; born July 26, 1945) is an American funk and soul singer. She is a performer known for her memorable and noteworthy live performances.
As a model in 1966, Betty first met jazz musician Miles Davis, who was 19 years her senior. At the time he was separated from his first wife, dancer Frances Davis, and was dating actress Cicely Tyson. Betty began dating Miles in early 1968, and they were married in September 1968. In just one year of marriage, she influenced him greatly by introducing him to the fashions and the new popular music trends of the era. In his autobiography, Miles credited Betty with helping to plant the seeds of his future musical explorations by introducing the trumpeter to psychedelic rock guitarist Jimi Hendrix and funk innovator Sly Stone. The Miles Davis album Filles de Kilimanjaro (1968), which features a photo portrait of Betty on the cover, includes a song named after her.
