The singing competition gets a bit of a reboot in Season 4 as Usher and Shakira temporarily replace judges Cee Lo Green and Christina Aguilera in the spinning chairs. Supposedly, the absent judges are just taking a break to go on tour and promote their new albums. In the meantime, the newbies will face off with Levine and Shelton and go through the motions to crown a new winner.
