The Britain's Got Talent judges have said they are all getting a thrill out of the show's new "golden buzzer".
The exciting twist to the ITV talent show gives judges Simon Cowell, David Walliams, Alesha Dixon and Amanda Holden the chance to choose one favourite act to send straight through to the live rounds, by hitting their golden buzzer, regardless of what their fellow panellists think.
Show boss Simon revealed as they kicked off auditions at London's Hammersmith Apollo: "It was on the German version of the show, they used it and it worked really well for them, so we thought we'd do the same thing here."
Amanda has already hit her buzzer, and described what a rush it had felt.
"It was an act that started off normally, even dull I would say, and then it went nuts and I could not believe it," she revealed.
"The audience were on their feet and I thought 'Oh my God! I'm going to do it!' And I pressed it, and all this gold stuff fell down from the ceiling and everyone went nuts. It was amazing."
But David and Alesha admitted they are being more cautious about giving away their golden ticket to the live finals, even as the auditions neared their end.
Little Britain star David explained: "I think you've got to go on your instinct, because it's a strange one - you don't know what's coming. I've got to see something that excites me and maybe something that the others don't believe in but I do. It's hard to say really, because you've got to be in the moment."
Singer and dancer Alesha warned that after seven series of the show, the judges' expectations were much higher.
"It's not necessarily that I'm going to press my golden buzzer for a dance act, but I love dance, I love singing, so when those acts come out on stage I tend to get quite excited at the prospect of them being great. And when they don't deliver anything different it's sometimes disappointing.
"Because our expectation has gone up. This is a global show, people watch it all around the world. And we want the winner of Britain's Got Talent to be incredible. So we're not settling for mediocre - we want the talent to be superb."
Meanwhile presenters Ant and Dec told how they recently replaced Simon on the judging panel for the ITV show in Manchester, after the TV mogul fell ill.
Dec said: "It was really hard because we'd been talking to all the acts backstage and we're on their side, so to have to hit the buzzer you immediately apologise and say 'I'm really sorry'."
He added: "I don't think we'll be rushing back to be judges any time soon!"
