A cool video has emerged from Denver, Colorado of a shy fan performing a duet with singer Jessie J.
The former judge on singing talent show The Voice was in America on tour when she invited the fan on stage.
In the video, which was filmed last month, fan Vonny Bennett understandably struggles initially with stage fright.
'Now you know what I can hear,' Jessie tells Vonny, pointing to the crowd. 'You can't hear them.' She then asks her if she would like a drink to calm her nerves: 'Relax, it's really not as hard as it seems.'
Thankfully, Jesse is an old hand at this, and she reassures her: 'The one thing I've learnt over the years, the more nervous you are, kind of the better. You just have to get to know your nerves.'
With her wise words on board, Vonny is then told: 'Don't be scared,' and asked which song she would like to sing. 'Price Tag,' says Vonny.
By the end of the video Vonny is owning the stage like a veteran pop star would.
