Diana Ross (born Diana Ernestine Earle Ross, March 26, 1944) is an American singer and actress. During the 1960s, she helped shape the Motown sound as lead singer of The Supremes, before leaving the group for a solo career on January 14, 1970. Since the beginning of her career with The Supremes and as a solo artist, Ross has sold more than 100 million records.
During the 1970s and through the mid-1980s, Ross was among the most successful female artists, crossing over into film, television and Broadway. She received a Best Actress Academy Award nomination for her 1972 role as Billie Holiday in Lady Sings the Blues, for which she won a Golden Globe award for. She won awards at the American Music Awards, garnered twelve Grammy Award nominations, and won a Tony Award for her one-woman show, An Evening with Diana Ross, in 1977.

In 1976, Billboard magazine named her the "Female Entertainer of the Century." In 1993, the Guinness Book of World Records declared Diana Ross the most successful female music artist in history with a total of eighteen American number-one singles: twelve as lead singer of The Supremes and six as a soloist. Ross was the first female solo artist to score six number-ones. This feat puts her in a tie for fifth place among solo female artists with the most number-ones on the Hot 100. She is also one of the few recording artists to have two stars on the Hollywood Walk of Fame—one as a solo artist and the other as a member of The Supremes. In December 2007, she received a John F. Kennedy Center for the Performing Arts Honors Award.

Including her work with The Supremes, Ross has released 67 albums. Ross is a soprano.
