The executive producer of The Voice US has said that the show's 'mentors' can never leave.
Chatting away to Billboard about the new 'season' (series) of the show, Mark Burnett announced: "Here's the fact we decided: When you've been on this show, that's your chair for life."
"So if they have to tour and someone comes in for a season and then goes out for a season, comes back for a season, there will never be anyone getting replaced, ever."
Blimey. Imagine if we were lumbered with the singer from The Script forever.
Aware of the fact that some of them have careers to attend to (even Christina), he added: "It's going to be moving pieces all the time. And luckily maybe a couple of them go on tour, a couple of them don't go on tour. They have an obligation to their fans. And so that's how we're going to do it."
