FILE - This Nov. 20, 2011 file photo shows Christina Aguilera performing at the 39th Annual American Music Awards in Los Angeles. Aguilera is comparing her upcoming album to a "rebirth." With more than a decade in the music business behind her, the album will be a culmination of "everything I've experienced up until this point," the pop star said, including divorce. The album doesn't have a release date and the title hasn't been announced. Aguilera, a coach on NBC's singing contest, “The Voice,” will perform the first single, "Your Body," on the show on Sept. 17. (AP Photo/Matt Sayles, file)
