EW.com reports that the R&B crooner and Latin singer will step in as coaches for Cee Lo and Aguilera, who are expected to return to the show in the fall.
Executive producer Mark Burnett explained the move, saying, "Having award-winning artists as coaches means they need to be able to tour ... Whether in the red chair or on tour, our coaches have their chairs for life. This is exactly why, after three seasons, we needed to allow them to rotate out so they can get on the road amongst their fans. Meanwhile, we're incredibly excited to have singular artists like Usher and Shakira joining the fold."
Their break from the show will allow Aguilera and Cee Lo to focus on their ongoing music projects. Aguilera will be going on tour as she prepares to release a new album, while Cee Lo is working on new music as well as a new sitcom based on his life.
The Voice airs Monday and Tuesday nights at 8/7c on NBC.
