Nick has yet to release any sort of public statement explaining why he’s leaving the show. Ultimately, the decision to leave may have been out of his hands. Gwen Stefani will be returning for the show’s 19th season. Previously, Gwen was a judge on Seasons 7, 9, 12, and 17, and she also worked on Seasons 8 and 10. She only missed 18 because its shooting schedule interfered with her Las Vegas residency, which was originally set to go through May.
Because of the coronavirus, Gwen’s Vegas residency ended early, two days before filming on The Voice began. Gwen has a personal connection the show, of course, as she’s dating Blake Shelton, who is the longest-serving judge on the series. At this point, it’s unclear whether Nick will ever return to the coach’s chair.
