Michael Bublé was lost for words after he bought a fan onto the stage at his concert in Buffalo, and she performed a song.
Bublé had announced to the crowd that he was going to pick someone to perform on stage with him.
Moments later, a lady named Nicole was brought up on stage and told Bublé that she would be singing "Hallelujah" by Leonard Cohen.
Michael was without a doubt blown away by Nicole's performance!
Have a look at her singing above.
