Powerhouse R&B singer Blige has signed on as an advising mentor for Adam Levine's team, Blige's rep confirmed to The Hollywood Reporter.
With nine Grammy Awards and four American Music Awards to her name, Blige will bring plenty of wisdom and experience to share with the aspiring singers.
"I've always been a huge fan of Mary J. Blige," Levine recently told Rolling Stone. "So it's been great having her on The Voice as an adviser to my team."
The announcement of Blige's role on the show comes on the heels of her announcement of her co-headlining tour with R&B singer D'Angelo, which will kick off on Aug. 18. She also recently starred in the movie musical, Rock of Ages.
Buble will be serving as a guest mentor on country singer Blake Shelton's team, NBC announced. The soulful crooner has won three Grammys in his career, and sold more than 30 million albums worldwide.
As mentors, both Blige and Buble will meet with contestants and give them tips before their performances. NBC has yet to announce the mentors for Cee Lo Green and Christina Aguilera's teams, so several other big names in music could possibly drop by the show in the upcoming season.
Previous mentors on The Voice have included Kelly Clarkson, Miranda Lambert, Alanis Morissette and Robin Thicke.
The third season of The Voice premieres on Sept. 10 on NBC.
