The Voice coaches may be up against each other in the show's grand final this weekend, but they'll be teaming up on stage for a sing-song.

It has been revealed that Sir Tom Jones, Jessie J, Danny O'Donoghue and Will.I.Am will be joining forces on Saturday night for a performance.

The BBC talent show's Twitter feed teased: "In other news, did we mention that our coaches are performing together on Saturday?

"They are. And one might describe the song as 'a banger'."

The judges all have a contestant they coach in the final - Leah McFall, Matt Henry, Mike Ward and Andrea Begley will be competing for the ultimate prize of a record contract in the final.
