John will join mentors on the show including Kelly Clarkson, Robin Thicke and Jennifer Nettles. The show will be set up so each mentor gets to select two contestants. Each week a contestant and mentor will sing together in — you guessed it — a duet for a live audience. The winner will walk away with the grand prize of a recording contract with Hollywood Records!
