Michael Buble, Mary J. Blige To Join 'The Voice'

The four coaches of NBC's "The Voice" each pack hefty enough chart-topping pedigrees themselves. As if that wouldn't be prestigious enough tutelage, Blake Shelton and Adam Levine have added two hit-making consultants between them with a combined nine Grammy wins.

The Hollywood Reporter (via Billboard) announced Friday that Mary J. Blige and Michael Bublé will join the primetime competition's third season as advisors respectively to Team Levine and Team Shelton. Like Kelly Clarkson, Miranda Lambert, Robin Thicke and Alanis Morrissette before them, Blige and Bublé will meet with contestants pre-performance to work out kinks. Mentors have not yet been announced for fellow panelists Cee-Lo Green and Christina Aguilera.

"I've always been a huge fan of Mary J. Blige," Levine told Rolling Stone. "So it's been great having her on 'The Voice' as an adviser to my team." Blige just announced a fall tour kicking off Aug. 18 with D'angelo, following her turn this summer in the stage-to-screen jukebox musical "Rock of Ages."

To date, Blige has to her credit nine career Grammys and four American Music Awards. Bublé has sold more than 30 million records worldwide en route to three Grammys of his own.

The third season of "The Voice" premieres Sept. 10 on NBC.
