Brooks & Dunn announced the news by posting promotional photo of themselves standing alongside Shelton on Instagram and captioned it: "This just in. We're joining #TeamBlake as Battles Advisors this season on @nbcthevoice! We're coming for you @blakeshelton!".
Meanwhile Levine has confirmed his pal Puth will mentor his team throughout the show's upcoming 16th season.
Puth isn't new to "The Voice" - he served as Alicia Keys' team mentor on the show's 11th season in 2016.
"He's mega talented and he's my friend and he's cool and I love him," Levine told Entertainment Tonight.
"What's really awesome about Adam is that he has a great musical ear," Puth added. "I call him, like, the best A&R in the music industry. He has a great idea of, like, who should be paired with who and makes great suggestions."
"I'm just along for the ride. It's kind of nice to see everything unfold in front of me and watch him make suggestions and I throw something in too."
Ballerini and Clarkson announced their pairing on news show Extra with the country singer stating, "I feel like I'm learning from what she's (Clarkson) saying, so I feel like I'm being way more quiet, because I'm listening to everything she's saying."
Kelly added, "She's being nice. It is just because I talk too damn much."
Clarkson won "The Voice" last season.
The show's 16th season begins on February 25 with John Legend making his debut as a judge and coach.
