The country superstar is officially joining Team Blake this season to help mentor Blake Shelton's contestants as they navigate the competition, NBC confirms to PEOPLE exclusively.
"He's really been good to me, and so the fact that I was able to get him here and and advise my team made perfect sense to me because he was actually a mentor for me," Shelton shares.
"If you know anything about country music, you know who Brad Paisley is. He's entertainer of the year. He's male vocalist of the year. He's sold millions of albums, and sold out tours. He's just one of the more respected singers. and just [among] people in the music industry and Nashville.”
Paisley, 42, first visited The Voice in the show's first season when he and Shelton, 39, performed their duet "Don't Drink the Water," and the two also toured together that same year.

"I wouldn't want to do this with anyone else – he's a blast to be around," Paisley said of Shelton. "We debuted [in country music] roughly around the same time … And we toured together in the struggling years. We have some great memories that I wouldn't trade for anything."
Season nine of The Voice returns Sept. 21 at 8 p.m. ET on NBC.
