Elizabeth Wagmeister Senior Correspondent After more than a decade ago on “The Voice,” Blake Shelton is preparing to say goodbye. NBC has announced that the next season of the singing competition will be Shelton’s last. Shelton has served as a coach on “The Voice” for all of its 22 seasons. Season 22 is currently airing on NBC, and Season 23, which airs in the spring of 2023, will be his last. “I’ve been wrestling with this for a while and I’ve decided that it’s time for me to step away from ‘The Voice’ after season 23,” Shelton said in a statement. “This show has changed my life in every way for the better and it will always feel like home to me.”
