And the battle of the singing shows continues! After “American Idol” announced its all-star lineup this week featuring Mariah Carey, Nicki Minaj and Keith Urban, their rival show, NBC’s “The Voice” followed suit with a major announcement of their own.

NBC announced that Usher and Shakira will be joining “The Voice” as new coaches next spring when Christina Aguilera and Cee-Lo Green take breaks from the show to focus on their careers.

The network said original coaches Adam Levine and Blake Shelton will remain on board next season.

Aguilera is reportedly going on the road to support her new album “Lotus,” while Cee-Lo is working on a new album of his own, as well as a Las Vegas residency, a memoir and a new NBC sitcom based on his life.

Both Aguilera and Cee-Lo are expected to return to “The Voice” next fall. The singing contest began airing its third season last week.
