Gwen Stefani may be bringing a new voice to "The Voice."  

Sources tell the No Doubt frontwoman is close to finalizing a one-season deal to fill Christina Aguilera's red chair on the hit talent search competition.  Aguilera, who is pregnant, is expected to rejoin "The Voice" as a coach next spring.  Stefani will join new coach Pharrell Williams, who is replacing CeeLo Green on the show's upcoming seventh season.

 "Voice" vets Adam Levine and Blake Shelton are also expected to return.  NBC has not confirmed the Stefani addition.



The coaching lineup on the current season of "The Voice" include Levine, Shelton, Shakira and Usher.
