If you tune into Britain's Got Talent every Saturday night, you'll know that a golden buzzer moment is certainly the most magic part of the show.

But for those not in the know, each BGT judge is allowed to hit the golden buzzer for one act each series, with that talented individual sent straight through to the live shows.

Golden buzzer moments have been rather eventful in the current series, which all started off with new judge Bruno Tonioli pressing his golden buzzer for brilliant dance group Ghetto Kids during the act.

While watching on the TV, a golden buzzer moment is built up as this magical science, with so much emotion on stage.

Of course, everything is made more dramatic on the tele for entertainment purposes, but some leaked BGT footage shows what a golden buzzer moment is actually like.

A video posted to Twitter shows the moment 11-year-old Olivia Lynes received the golden buzzer from Amanda Holden, after she gave a beautiful rendition of 'Defying Gravity' from Wicked.

And while it was rather magical on stage, the reality in real-life was a little less dramatic.

In a short two-second clip, filmed from the centre of the theatre, three men can be seen on the stage by Olivia as Amanda pressed her golden buzzer.

One man is holding up a machine to spray the golden confetti onto Olivia's head, while a second crew member is crouched down filming the 11-year-old, with the third member supporting him.

The footage was posted to Twitter by Adam Khan, who wrote: "Golden Buzzer reshoots aren't as cool looking in real life than all the slow-mo stuff you see on the TV... it's just a guy blowing confetti onto the contestant while cameras film in slow motion..."

Many BGT fans have flocked to the comment section of the leaked footage in disbelief as to how different the show is in real-life.

"Clips like these that shock how fixed this show is," one person wrote.

A second added: "It’s clips like this that the producers of #bgt recreate to make us think that we are all gullible and the fakery is real.

"Why can’t the show be more raw and real, it would be appreciated a lot more."

Meanwhile, a third remarked: "It’s true. A huge anticlimax."

Olivia's audition actually proved controversial itself, as Amanda went to go meet her before the show to invite her to audition.

It led to some fans calling the show a 'fix', after the judge awarded her golden buzzer to the 11-year-old.
