Bruno Tonioli made a 'Britain's Got Talent' faux pas when he pressed his Golden Buzzer for a second time.
The ITV show's new judge - who has replaced David Walliams on the panel - is said to have not realised he was only allowed to press the buzzer, which gives wannabes a direct passage from the auditions to the live finals, once during the series.
A source told The Sun newspaper: "It was madness. The buzzer worked but there was no glitter in the cannon above the stage as it had already been used up.
"A producer raced over to try to tell Bruno he couldn’t do that."
After Bruno's 'BGT' mishap, head judge Simon Cowell was said to have entered discussions with the show's producers about whether or not to let the act through.
The source added: "Then there were discussions with the top execs and Simon, who had his head in his hands.
"Then Bruno said he’d never actually watched before!
"Apparently it was because he didn’t want to be influenced by other shows’ judging styles.
"But he’s the big money new signing! Fortunately, the audience love him and just laugh at his blundering."
What's more, the former 'Strictly Come Dancing' judge is said to be "up and down like a yo-yo" from his seat during the auditions at the London Palladium, keeping the camera operators on their toes.
A source told the Daily Mirror newspaper: "Bruno is a little firecracker and constantly jumping up and down. The crowd loves it, Simon loves it ... but the camera operators, less so.
"It’s an undertaking keeping up with him. He is up and down like a yo-yo."
Bruno, 67, recently admitted he was "so excited" to be joining the panel.
He said in a statement: "Here we are, ‘Britain’s Got Talent’. I am so excited. It’s my first show, I have no idea what’s going to happen, but I’m sure it’s going to be brilliant."
