Christina Aguilera & Alicia Keys Perform On CNN's Heroes Special

Grammy winners Christina Aguilera and Alicia Keys performed on CNN Heroes special, which aired last night. Check it out:

Christina Aguilera - 'Beautiful'


Absolutely AMAZING. Christina, IMO, is the best female vocalist hands down, Mariah, Beyonce, Alicia, all take a back seat to her in that department, and its really evident why in this performance.

Alicia Keys - 'Superwoman'


Good Performance.
