Usher and Shakira will be subbing in for Christina Aguilera and Cee Lo Green during season four of “The Voice.”

For the first time since the singing competish’s debut, “The Voice” will hold back-to-back seasons, pedaling another cycle of the show out after the recently bowed third season closes. Aguilera and Green, mainstay judges for the skein, plan to fulfill other professional commitments during their coaching hiatus, and Usher and Shakira will step in to coach the fresh batch of crooning hopefuls.

During the break, Green will be developing music along with a scripted laffer based on his life for the Peacock, while Aguilera promotes her new album “Lotus,” set to be released on Nov. 13.

Current coaches Adam Levine and Blake Shelton will remain in their swiveling chairs during season four.

“We are thrilled to welcome Usher and Shakira to ‘The Voice,'” said NBC Entertainment chairman Robert Greenblatt. “Doing two back-to-back cycles of this show requires a tremendous amount of time, and we are happy to accommodate the commitments made by Christina and Cee Lo.”
