Aguilera's song joins Coldplay's 'Atlas' on the highly-anticipated movie's soundtrack and it will be called 'We Remain', reported Ace Showbiz.
"Love the underlying message of @TheHungerGames. 'We Remain' is a special new song, its message to my fans & how I connect with the movie, alike," Aguilera tweeted.
Rock band The National have also written a song for the second installment of 'The Hunger Games' trilogy.
The band's frontman, Matt Berninger, said that he and his bandmates had written a song called 'Dying Is Easy'. The title was then changed into 'Lean' because the film producer thought the original title was "too dark."
