Blake Shelton’s rep confirmed to ET that the country crooner will also return as a full-time judge next season. No word on whether or not Williams, longtime judge Adam Levine, or Shelton’s girlfriend, Gwen Stefani, will be returning to fill the fourth spinning seat, but it will certainly be a more girl-powered panel than in seasons past.
