Beyoncé‘s new CD was inspired by Deena, the Diana Ross-like character she plays in the upcoming film Dreamgirls, and she looked an awful lot like her diva forebear (circa ’79, below left) at the BET Awards in June (right). Plus both were girl-group leaders (the Supremes vs. Destiny’s Child) before going solo. For Miss Ross’s finest, check out The Boss (’79) or Diana (’80).
