For any Glee fan, the name "Amber Riley" is practically synonymous with goosebumps. The 31-year-old singer and actress has one of the most incredible voices on the planet and is currently showing off her talents in the West End's production of Dreamgirls as Dreamettes member Effie White. While at the Olivier Awards in London on Saturday at the Royal Albert Hall, Riley not only took home the award for best actress in a musical, but also hit the stage to perform her biggest, most dramatic number from the show, "And I Am Telling You I'm Not Going." It's an absolute knockout of a performance, and a reminder that her voice is truly unreal. Also, she might've gotten some Hamilton tickets out of the deal!
