The Voice's Mentor Shuffle

MUSICAL CHAIRS: NBC’s The Voice, which has jumped ahead of Fox’s The X Factor in its third season, will shuffle its own line-up for next spring’s fourth season when it replaces Christina Aguilera and Cee Lo Green with Shakira and Usher, according to a report in Us Weekly. NBC is developing a new show for Green, while Aguilera will be committed to promoting her upcoming album Lotus. Fellow mentors Adam Levine and Blake Shelton are expected to remain, but network officials would not comment on the report, though other sources say Aguilera and Green could return for future seasons.
