Talk about hearts bursting and breaking from a breath taking performance by A Great Big World and the iconic Christina Aguilera at the 2013 American Music Awards last night.

The deep and sorrowful song is already lovely by itself but adding Christina’s perfect pitch made it out of this world. You could tell how into the emotional song she was and looked stunning with simple makeup and a classic black maxi. She was just perfection!

Check out the song and have your heart just sigh.
