Christina Aguilera Sings for a Cause [VIDEO]

I know it's really easy to get caught up in our lives. The hundreds of things we have to do, the complaints we have about work. Shoot, I get caught up in MY life everyday. How good would it feel, though, if we took the time every once in a while to help someone who might be a little worse off than we are?

Christina Aguilera has taken the time to sing in a PSA for World Hunger Relief and it's amazing how far a dollar can go.
