Has Christina Aguilera given a bad rendition of A Great Big World duet Say Something, yet? If she has, I haven't seen it!
It was no different when they performed at Wango Tango, with the Diva giving effortless vocal. If this song wasn't an advert for the singer to stay within - or at least near to- her tessitura, than I don't know what is!
Beautiful!
Thoughts?
