These singing competition shows are having switcheroos all over the place! We saw Britney Spears and potentially Khloe Kardashian joining X-Factor, Mariah Carey, Nicki Minaj and Keith Urban joining American Idol (in place of J. Lo and Steven Tyler) and now, Christina Aguilera and Cee-Lo are out for season 4 of The Voice, being replaced by two equally…if not more…famous voices. No worries, though, Xtina and Cee-Lo fans: they’ll be back for season 5! Who, what and why? Details below.

“The Voice” is singing a new tune. NBC’s singing competition has hired Usher and Shakira to fill in for Christina Aguilera and Cee Lo Green next season.

The R&B superstar and Colombian bombshell will coach on the spring edition of the series, while Green and Aguilera take breaks to focus on their careers. Both are expected to return to the show next fall.

Aguilera will spend her time promoting her upcoming album Lotus. “Since this year NBC and ‘The Voice’ have decided to tape back-to-back seasons, requiring a full-year commitment, it is important for me to take season four off, allowing me to support my music that my fans have been waiting for—with the release of my new album Lotus on November 13,” she said.
