Christina Aguilera is returning to "The Voice" as Shakira and Usher will not be returning to the show.
Although ratings have been down slightly, Shakira and Usher will not be returning. Shakira's reason is to spend time with her newborn child and Usher's is that he will be working on a movie.
Adam Levine and Blake Shelton will be joining Christina. Also, there is word that Cee Lo Green will be back as well.-DocFB
