This explosive actress, whose work has been described as breathtaking and soulful, is originally from St. Petersburg, Florida and is the youngest child of Henry and Minnie Sellers, who strongly encouraged education, music and artistic creativity.

In St. Petersburg, Diane attended Azalea Middle School and Dixie Hollins High School, where she performed in numerous stage productions and sang in many talent shows. She knew she was destined for a career as a performer when her sister, Dolores, escorted her to her first professional audition, a touring stage musical titled Sights and Sounds, wherein Diane was described as the cast's "triple threat," as an actress, singer and dancer.
