Click on to read the surprise that the Oscars’ producers are planning for Sunday’s telecast. Hint: It has to do with the cast of Dreamgirls.

Deadline Hollywood Daily reports that Oscar telecast producer Laura Ziskin and Dreamgirls director Bill Condon have planned that each of the Dreamgirls — Beyoncé, Jennifer Hudson, and Anika Noni Rose — will sing each others’ songs from the movie. Diana Ross, on whose life the Motown musical is loosely based, was asked to sing one of the Dreamgirls songs on the Oscars. But she said no, telling the producers, “I’m not interested in promoting that movie.” She still claims she hasn’t seen it.
