The judges of Britain's Got Talent had a brief moment of panic on Sunday night when Bruno Tonioli made a massive error.

It was a bit of a mess during the live semi-finals over the weekend when judge Bruno was blown away by singer Gamal John, who performed 'It's A Man's Man's Man's World'.

Bruno, who's the newest judge on the panel, was so impressed by the performance that he couldn't resist in pressing the Golden Buzzer - which would usually be fine... except for the fact that he's already pressed it this season.

For those not in the know, each series a judge gets just one opportunity to press their Golden Buzzer.

Bruno had already pressed the life-changing button earlier this season, when he watched a dance group called Ghetto Kids perform.

So, when he pressed it for a second time, even BGT veteran Simon Cowell wasn't sure how to react.

After singer Gamal John finished his performance, the whole crowd started chanting 'press the buzzer'.

And even though both Alesha Dixon and presenters Ant and Dec explained that there were no buzzers left, Bruno insisted that he 'had to do it'.

So, without thinking, Bruno got up out of his chair and pressed the Golden Buzzer, leaving the entire audience - and the judges - in shock.

"What the hell? That's not allowed!" called out Ant from the side of the stage.

While Simon held his head in his hands, Amanda grabbed Bruno by the arms and told him: "You only get one! Oh my God, this is chaos."

Alesha exclaimed: "What have you done to this show?!" while Simon joked: "Erm we are about to get fired."

Despite the mix-up, it looks like the BGT team might let Bruno get away with it.

"Having said that, Bruno is a new judge and if you give something you can't take it away," Simon told the audience.

That gave Ant and Dec all the motivation they needed to sprint out on stage with a confetti canon, shooting it over Gamal and his son as they celebrated.

Later on, Bruno apologised to fans at home for the blunder, telling the official Britain's Got Talent social media page: "Oops, I did it again!

"I mean, I'm sorry, I just, I had to. I mean, the theatre, literally they were shaking the ceiling.

"I had to do it. I mean, I can't explain it because they deserved it. There you go, I'm sorry!"
