Christina Aguilera Records Cover Of A Great Big World's 'Say Something'

Christina Aguilera is apparently a huge A Great Big World fan. She teamed up with the upstart orchestral-poppers to record a new version of their breakout hit "Say Something." The song is a beautiful, simple track that only gets better with Aguilera's legendary vocals.

Check out the band's shock at getting a request from Christina as well as interviews with the lady herself over a preview of the track below:

Aguilera hasn't released an album since last year's Lotus but did release the epic track "We Remain" from the soundtrack to the upcoming film Hunger Games: Catching Fire.
