Once again we come bringing you a video from "Britain's Got Talent". This talent show is just an endless string of surprises, one better than the other!
We have already seen conjurers who almost made us believe in magic, children with amazingly powerful voices, dancers, musicians, contortionists, jugglers and even some death-defying acts.
But in this case the judges got to witness something that hadn't ever happened before. Little did they know that the audience had been infiltrated and the people hiding in plain sight were only waiting for a signal to start a commotion…
Not every flashmob performance is successful, but this one was a total win! Must have been because of the song they had chosen!
