'The Voice' finale aired December 17th 2019 in which team Kelly member Jake Hoot was deemed the winner. However, 'The Voice' finale wasn't just the end of the season, it was also the end of coach Gwen Stefani's time on the show. Nick Jonas will be taking Stefani's place next season.
However, Stefani's time on 'The Voice' was spent sporadically. She coached on seasons 7, 9, 12 and 17. So this may not be her last time on the hit singing competition.
