Diana Ross — $250 Million

Legendary singer and actress Diana Ross has a net worth of $250 million. Originally a member of the singing group The Supremes, Ross went on to enjoy an internationally successful solo career. She is the only music artist in history to have #1 songs as a member of a duet, as a solo artist, and as a member of a musical trio. Between her various singing investments, Ross has sold a whopping 75 million albums worldwide.

Her eponymous solo debut album was released in May 1970, which is quickly followed by the albums Everything is Everything and Surrender. In late 1971, Ross starred in her first television special Diana!, and at the time, she began negotiations to leave the Motown music label. She then went on to sign a $20 million contract with RCA Records, which was considered the most expensive recording deal in music history at the time.
