With a judging panel already consisting of Adam Levine, Blake Shelton, Cee Lo Green and Christina Aguilera, more stars are ready to shine on "The Voice" when it premieres on CTV Two September 10th.

Rob Thomas, who will team up with Green, Mary J. Blige, who will accompany Levine, and Michael Bublé, who will saddle up with Shelton, have all signed on as mentors to assist in the developmental process of each judges’ group of competitors . A celebrity has not yet been named to join Aguilera’s group.

Thomas, who is the frontman of Matchbox Twenty, won three Grammy awards in 1999 for his collaboration with Carlos Santana on the hit song "Smooth." He also parlayed his band’s success into a successful solo career, reaching the top of the charts in 2005.

Blige, 41, has been called one of the truest R&B queens to ever grace the stage. She is a nine-time Grammy winner and has sold in excess of 50 million albums in her career. In 2012, Blige was #2 on Billboard Magazine’s list of the top-50 R&B and hip-hop artists of the past 25 years.

Bublé will become the second Canadian chosen for a mentoring role on the hit show, following in the footsteps of Alanis Morissette. He is a three-time Grammy winner and has sold more than 30 million albums worldwide. Bublé already has advising experience, having previously appeared as a mentor on the UK’s "X Factor."
