Christina Aguilera & Alicia Keys Perform Live at CNN Heroes

Christina Aguilera and Alicia Keys both performed on CNN Heroes special last weekend. On the show which aired last night, Christina performed her hit song "Beautiful" and Alicia sang "Superwoman". Both ladies did an incredible job, Christina especially, she sounded amazing, the best I've heard her sing in a long time.
