Jonas broke the news on “The Ellen DeGeneres Show” during an episode set to air Tuesday.
“I am so excited about this,” he said. “You’re basically the first people I’ve told, so thank you for being a part of this special moment for me.”
The announcement came after DeGeneres showed some videos from current coaches Blake Shelton, Kelly Clarkson and John Legend.
“I’m going to have to look through the rules because this is my TV show,” Shelton joked in his clip. “I’m not even sure if you’re old enough to be a coach on ‘The Voice,’ but I’m certain that you’re going to get your butt kicked, buddy.”
Jonas jokingly offered his response to Shelton.
“Just to be clear, Blake, I’m going to kick your a**,” Jonas said.
Jonas tweeted a video Monday night expressing how happy he was to be joining the NBC hit.
“I’m hoping for a Season 1 win for Team Nick and a chance to work with some amazing talent,” he said.
He’s not the first Jonas to be a part of the franchise.
Brother Joe Jonas has served as a coach on Australia’s edition of “The Voice.”
