To avoid complications with contracts, it's possible that she decided to keep Diana as her stage name.
Head of Motown Berry Gordy changed the name of the group to The Supremes.
Also in 1971, she was the host of a TV special, Diana!
She then took a five year break to raise a family, interspersing the sabbatical with duets with Marvin Gaye and the recording of an album of love songs.
Diana Ross is an unusual artist, having achieved fame across a number of different musical genres.
The Supremes with Diana as lead singer had two more number-one hits before Diana went solo in May 1970.Diane Ernestine Earle Ross was born on 26 March, 1944, in Detroit, Michigan, USA, the second of six children.Her parents were Fred Ross (born 4 July, 1920) and Ernestine Ross-Jordan (1916 - 84).Barbara Martin left The Primettes just before the girls signed for Motown.Detroit State labour laws require proof of age before a minor can obtain employment, so it is possible Motown's clerical staff saw the birth certificate which stated her name as Diana.
As their popularity grew, it became clear that Ross was more than just the frontwoman; Gordy changed the name of the group to 'Diana Ross and The Supremes' in 1967 to take advantage of Diana's celebrity status.
