"'Almost Home' has a message that works beautifully with the film," the new "American Idol" judge says of the song she both co-wrote and co-produced. "It's a feel-good record, evoking the feeling of reaching your home and being with people that you love."

Famed artist/photographer David LaChapelle will direct the music video. He worked with Carey in the past on 2001's "Loverboy."
