Christina Aguilera is 100 percent returning to “The Voice” for season 10, Gossip Cop has exclusively learned. After it was announced on Wednesday that Gwen Stefani was rejoining the singing competition show for season 9, rumors online began to spread about Aguilera and her future involvement with the show. A rep for Aguilera tells Gossip Cop that the singer “doesn’t do back-to-back seasons,” but wouldn’t comment beyond that.
