Oprah Winfrey is reported to have cast R+B singer Alicia Keys in the lead role in her forthcoming biopic on LENA HORNE. The U.S. chat show queen-turned movie producer has chosen the Fallin' hitmaker to play the reclusive jazz star, who is now 90 years of age. She says, "We're going to start filming next year, and we've got Alicia." Singer Janet Jackson is reportedly devastated by the news, as she had actively pursued the role of Horne for years - and was in talks to play the music legend when the project was earmarked for a TV special.
