This news is BREAKING this morning. E! is reporting that Maroon 5 frontman Adam Levine is leaving The Voice, where he has been a coach for the entire 17 season run of the show. Apparently, the decision to leave was his. Reports are also saying that Gwen Steffani (from Do Doubt) will be replacing him. This actually creates a really interesting set up on the show as, of course, Gwen and fellow judge Blake Shelton have been a couple for years. So, the couple will be competing with each other for contestants on the show! The show's host, Carson Daly, made the announcement this morning on The Today Show.
