If she is nominated and takes home the Oscar, the multitalented star would achieve EGOT status. She already has won a Daytime Emmy, GRAMMY and Tony Award -- all for her performance in the Broadway revival of The Color Purple.
"You'll learn a little bit about her life behind the music -- the thing that made her a genius," she explained. "You'll learn about some of the darkness in her life. You'll learn a lot of music; some music you might not know. I'm singing everything live, so you'll hear all that."
