Managed to eke out a thanks to the original stage Effie, Jennifer Holliday, as the orchestra music began to unceremoniously drown out Jennifer's emotional Oscar acceptance speech. Both Holliday and Sheryl Lee Ralph (the theater's first Deena) had expressed hurt and dismay earlier at being snubbed during the mounting publicity for the "Dreamgirls" film. The third original Dreamgirl on stage, Loretta Devine, received a singing cameo in the film version. The other two were not offered or even approached to appear in the film.

A revival of the 1981 Broadway smash "Dreamgirls" is in the talking stage and Jennifer has been approached about recreating her Effie role.

Is one of four African-American actresses to win an Oscar in a competitive category. In chronological order the others are: Hattie McDaniel for Gone with the Wind (1939), Whoopi Goldberg for Ghost (1990) and Halle Berry for Monster`s Ball (2001).

Began singing when she was 7-years-old. As a child, Jennifer performed as part of a choir at her local church in Chicago.

Jennifer's role of Effie Melody White in Dreamgirls (2006) is a thinly-disguised portrait of the late ousted Supreme Florence Ballard. Flo's story, however, ended up tragically, unlike that of the Effie character. Of Diana Ross and Mary Wilson, Ballard, who gave the Supremes its name, was the strongest vocalist of the three and all three girls at one point shared leads. Labeled the "No-Hit" Supremes for a time, astute Motown mogul Berry Gordy decided Ross had the ideal personality and coy voice to pull in cross-over white audiences. He was right and the Supremes were a sensation with Ballard and Wilson shoved permanently into the background and never given any solo lines in any of their hits. Unlike Effie, Ballard's weight was not a factor until well into stardom, fed by Ross's diva-like stance, Flo's ongoing depression and problems with alcohol. Ballard's unreliability for shows triggered her dismissal in 1967 and an attempted solo career was a complete bust, never allowed to feed off the Supremes name for publicity. Ballard became destitute with three children to support and her health severely declined. Unlike Effie, Flo never was able to make a comeback and died of a coronary thrombosis in 1976 at age 32.

Jennifer attributes her vocal talents to her late grandmother Julia Kate Hudson, who was a former choir mistress in Chicago.
