We're back for battles as once again Christina Aguilera, Blake Shelton, CeeLo Green and Adam Levine pair their best artists together to compete for a chance to move on. The superstar coaches will mentor their artists along with their friends Mary J. Blige, Michael Buble, Rob Thomas and Billie Joe Armstrong. After three battle episodes, the stakes are getting higher for everyone. Adding to the pressure, the coaches realize that anyone they let go after a battle is subject to being stolen by a fellow coach.
