Christina Aguilera and A Great Big World - Say Something - Official Music Video

Christina Aguilera has teamed up with A Great Big World for a new collaboration. "Say Something" is a haunting piano ballad that features the softer side of Christina's vocals.

I think they sound great together. The Voice judge has always been able to deliver a ballad. They really blend well and it creates a powerful and emotional video.

Christina looks fantastic!
