NEWS: Usher (@UsherRaymondIV) To Replace Cee-Lo (@CeeLoGreen) On 'The Voice'?

Looks like American Idol isn’t the only ones making changes. When NBC’s The Voice returns for its fourth season this spring, two of the spinning chairs will be filled with new faces. Cee Lo Green and Christina Aguilera will be taking some time off from the show and stepping down as coaches for season 4. They will be replaced with R&B star Usher and Latina singing superstar Shakira.

The move is primarily due to the fact that the show has expanded to two seasons per year instead of just one. Aguilera is planning to go on tour to promote her new album while Cee Lo is developing a sitcom for NBC, but doing The Voice from September to May doesn’t give her a lot of free time.

However, seasons 1 and 2 winners Adam Levine and Blake Shelton will remain as coaches for season 4, so it won’t become an entirely different show. It’s also likely that Xtina and Cee Lo will return for future seasons, if NBC continues to air The Voice.

The Voice has certainly scored some top-tier talent for the new chairs. Between Shakira’s hips and Usher’s smooth moves, Adam Levine is going to have some stiff competition in terms of sexiness.

The new coaches will also give The Voice a competitive edge when it goes up against American Idol in the spring, since the latter just booked a panel of new judges including Mariah Carey, Nicki Minaj and Keith Urban.
