This songbird is the epitome of selfless when it comes to her efforts to help underserved youth. She co-founded Camp Mariah, giving disadvantaged children a chance to explore the arts and guidance on their future careers. She has performed various charity performances including Live 8 in London, and the Shelter from the Storm telethon for victims of Hurricane Katrina. In November she announced that she would be the Celebrity Brand Ambassador to the American Heart Association's My Heart. My Life initiative. She too will join Mary J. Blige as a VH1 Diva for Charity later this month.
