Christina Aguilera has just finished her new album "Light & Darkness," which will come out next year. The upcoming album includes collaboratins with Flo Rida and Santogold, says producer Christopher "Tricky" Stewart. "The album is finished. She's mixing. She hasn't made a final decision about what the first single is, but I know everyone feels good about their options." "She's gonna do the film [Burlesque] first. She didn't want to not be able to promote this record because it's gonna be a big record for her," Tricky said.
