Now the famous foursome have announced they will all return to mentor a new bunch of wannabes for a second series.

NBC executive Paul Telegdy says, "Our fantastic coaches were integral to the tremendous success of The Voice this year and we are thrilled that they are all returning.

"We look forward to building season two and making The Voice an even greater experience for fans."

The show sees the judges choose acts they wish to mentor while only listening to their voice.
