Amber Riley - And I'm Telling You I'm Not Going (Olivier Awards)

Olivier Award winner Amber Riley, who won the award for Best Actress in a musical, took the stage to perform her big Dreamgirls number at the Olivier Awards in London last Saturday night. As it is known, Amber stars as Effie White, the lead singer of a fame-hungry trio from Chicago who finds herself edged out by their smooth-talking manager Curtis (and the guy she loves) just as the group, the Dreamettes, are hitting the big-time. Amber has received unanimous praise from both audience and critics alike.
