No doubt about this news: Gwen Stefani is in talks to join The Voice. A source confirms to E! News that the singer’s deal to join the NBC singing competition is close to being done. The mother of three would replace pregnant judge Christina Aguilera on the upcoming seventh season. Stefani would also join fellow newcomer Pharrell Williams, who was recently tapped to fill CeeLo Green’s spot. Blake Shelton and Adam Levine are expected to return. Filming will begin in June and the hit series will debut in the fall. NBC has made no comment so far on the matter.
