Christina Aguilera has teamed up with pop duo A Great Big World to perform their song "Say Something" next week on "The Voice." 

If A Great Big World sounds familiar to you, it's probably because you've heard their song "This Is The New Year," which was featured on an episode of "Glee" (see video below). Now, the singer/songwriter pair, made up of Ian Axel and Chad Vaccarino, were handpicked by Xtina to perform with her on her hit show.

Christina says, "I'm only taking on projects that feel good to me and represent a purpose of the 'here and now' in my life, and that's what this song 'Say Something' actually does for me." She tweeted about the collaboration Thursday, with a link to a behind-the-scenes look at the recording of the song.

A Great Big World's debut album, Is There Anybody Out There?, will be available for pre-order November 4th.
