The two-night grand finale of the NBC talent competition will begin on May 19 when all four coaches - Adam Levine, Blake Shelton, Shakira and Usher - will sing, reported Digital Spy.
Each of the remaining contestants will also be tasked with singing two songs, one of which will be chosen by their coaches and the other by fans via an online vote.
An all-star lineup has been announced for the following night on May 20 as OneRepublic, Coldplay, Sheeran and Tim McGraw take to the stage.

Coldplay's Chris Martin and OneRepublic frontman Ryan Tedder have both served as mentors on The Voice.
