Simon Cowell left viewers stunned as he ‘broke the rules’ on Britain’s Got Talent last night.

If one man can tear up the rulebook on the long-running ITV competition show it’s the main man himself.

As judges Cowell, Bruno Tonioli, Alesha Dixon and Amanda Holden sat down for another round of auditions for this year’s show, one act had such a huge impact on Cowell he had to make sure they had his ultimate approval.

Dance group Unity, which is made up of college pals, all aged between 16-25, wowed the judges with a performance that highlighted all the wonderful things that makes people unique.

One auditionee said: “I’m Junior, growing up I was bullied for my love of dance.

“Dancing makes me feel free, and allows me to act out my feelings in a safe place.

“Bullies ruined this, I was beaten up and called names, all because a boy loved to dance.”

They received a huge response from the audience who cheered and gave the group a standing ovation.

Former Strictly Come Dancing judge Tonioli gushed: “You can be anything you want and anyone you want to be.

“The message is loud and clear. The execution, artistically, your choreography was superb.”

After Holden was cut off by all the cheers from the audience, presenter Dec Donnelly said: “The audience want a gold but there aren’t any golds left.”

Referencing Tonioli breaking the rules by pressing the golden buzzer twice this series, Ant McPartlin added: “Bruno will push it anyway!”

As the audience chanted for the judges to press the golden buzzer, Tonioli told the group: “I have already done it twice, I can’t do anymore.”

Holden, who pressed her golden buzzer for 11-year-old Olivia Lynes after she performed ‘Defying Gravity’ from Wicked, said: “For me it was such a beautiful and passionate piece, the message was so strong.

"Everything that you stand for, all your personalities and the love that you have for each other, all the characters involved in this group.

"All of that made this such an amazing and special piece. It was beautiful."

Cowell said: "I actually thought that was astonishing, the way that you got your message across was so strong.

"It was an audition I will never forget. What you have done, you have done it your way. Look, we don't have any golden buzzers left."

"But sometimes I feel that you should break the rules," he said as he hit the buzzer despite them all being used up.

Pressing the golden buzzer automatically grants an act a place in the semi-finals, meaning they get to skip the bootcamp stage. Typically, the judges have one golden buzzer opportunity per series to press it for any act they decide.

As Unity were showered with gold confetti, Dec said: 'I don't know what's going on anymore!”
