How moving! Christina Aguilera has added her voice to a new song by the pop-duo A Great Big World, and the results are awesome. The collaboration came after Aguilera tapped the duo of Ian Axel and Chad Vaccarino to perform live on The Voice on Tuesday, November 5. After she heard the song, titled 'Say Something,' she asked to be a part of the track.
