Jonas made his The Voice coaching debut in Season 18 to fill Stefani’s slot at that point too, so it seems that he and Stefani are switching off seasons.
Season 19 also marks Gwen Stefani’s last chance for the foreseeable future to take a contestant to the top prize on The Voice.
Stefani is leaving the coaching chair behind yet again for Season 20, with Nick Jonas returning for a second season.
Jonas’ return should come as good news for fans who were sad to see him go after only one season, and it’s not impossible that Stefani will turn up during Season 20.
