Mary Wilson net worth: Mary Wilson is an American singer with a net worth of $8 million. Wilson gained her net worth as a member of The Supremes. Before The Supremes came into existence, Wilson along with friends Florence Ballard, Diana Ross and Betty McGlown were recruited by record producer Milton Jenkins (in the late 1950s) to become The Primettes. By 1961, the female act was signed to Motown Records, changing the name to the Supremes. The 60s act earned its place in music history as America's most successful vocal act. During the 18 year lifespan, The Supremes produced 33 top 40 hits and 12 number ones on the Billboard charts. Although the group went through many change of line ups, Wilson remained the only consistent member. After leaving The Supremes in 1977, Wilson embarked on solo career, releasing a few disco albums. She also took an interest in musicals, appearing in a string of plays. In the mid eighties, Wilson published the highly successful book, Dreamgirl: My Life as a Supreme, revealing shocking revelations about the group. In recent years, Wilson is still involved with music: in 2007 she released a jazz album, Up Close: Live from San Francisco. Also a dedicated charity worker, Wilson works alongside charities including UNICEF and NAACP.
