Cee Lo Green and Christina Aguilera are both coming back as judges on “The Voice” after they took a hiatus to work on their respective projects.

Aguilera left to headline a tour, and Green went on to focus his efforts on a Vegas show. Their big red chairs were kept warm by Usher and Shakira, who seem to have enjoyed their time on the show, but the original judges want their spots back. Aguilera has already signed her contract–which will pay her $12.5 million for a fifth season–and Green is negotiating his. The show has gained popularity in the last couple of seasons, and producers say they will continue to work with their celebrity judges in order to keep everyone happy.

“These are current touring artists, so it’s a matter of balancing schedules. They’re all in demand, and we’re just balancing it all,” executive producer Mark Burnett said.

Maroon 5 singer Adam Levine and country star Blake Shelton are also set to return for the next season.
