Amanda Holden risked flashing her underwear as she took on an impressive cartwheel for a hilarious Instagram clip.
The radio presenter, 53, and her Heart co-host Jamie Theakston went around central London asking the public to show their best skills as part of a series of fake Britain's Got Talent auditions.
The ITV's show judge stunned viewers and put on a very risqué display when she did a handstand in a tight one-shoulder turquoise midi dress and high heels.
In the hilarious clip, shared by Heart FM's Instagram, Amanda did the cartwheel but luckily her underwear was covered with a Union Jack flag.
Standing with her legs crossed, the TV star grinned from ear to ear proud of her result - lifting her arms in the air.
'@bgt... but on a budget @noholdenback,' the account captioned the video alongside a slew of laughing emojis.
Fans were left in stitches, racing to praise Amanda's impressive skills with one person commenting: 'A cartwheel in heels should be considered an extreme sport.'
'The cartwheel is a yes from me... lol'; 'Amanda Holden to start competing with that amazing cartwheel ❤️ @thisisheart @noholdenback'; 'Bloody brilliant'; 'Amanda is a pro!! doing a cartwheel in a dress and heels! ❤️x'.
For the funny gag, the Heart hosting duo asked random people in the streets to improvise their skills, leading to a series of hilarious moments.
A builder was seen cutting some shapes with a wheel in each arm, while another lady attempted to make realistic animal verses, and another person mirrored the presenter doing a cartwheel on the pavement.
Ultimately, Amanda gave an 'unofficial' golden buzzer to a girl called Amber who, at the end of the clip, showcased her astonishing vocal skills.
It comes after head judge Simon Cowell and Amanda engaged in a lively dispute on Wednesday's Britain's Got Talent.
Simon, 64, was playfully slapped by long-serving panelist Amanda as they battled for bragging rights over the festively named singer Sydnie Christmas.
Both claimed her as their Gold Buzzer act during Wednesday's live-semi final at Hammersmith Eventim Apollo, prompting an indignant reaction from Amanda - who originally gave Christmas a free pass to the latter stages of the competition in April.
With Simon attempting to claim the 28-year old as his own act, his fellow judge snapped back: 'No, you wish she was yours.'
Despite co-host Ant McPartlin confirming she was indeed Holden's chosen Golden Buzzer act, the head judge stuck to his guns as she talked over him, prompting her to give him a playful slap on the shoulder.
'She is absolutely phenomenal,' Amanda said, waving him off. 'I don't know what she's singing, I want to be surprised. But I know she's going to smash it.'
Kent-based gym-worker Sydnie sailed through to Sunday's final after stunning the judges with her version of Frank Sinatra's My Way.
She was joined by impressionist Mike Woodhams, with both now one performance away from winning a life-changing £250,000 cash prize and a spot on the bill at the Royal Variety Performance.
Amanda, who was brought to tears, told her: 'I have to sit down, I thought I was going to pass out during that. Honestly, Sydnie when we saw your audition I had so many people come up and stop me.
'And tonight you have done even better, I just cannot believe your capacity and your fire and your strength.'
An equally impressed Bruno Tonioli added: 'I cannot believe it. The way she builds up to the high note, hitting it with such power and clarity. It was stunning, stunning.'
Alesha Dixon was in agreement, telling the singer: 'My heart was pounding the whole way through that. That is the job of a singer, you are a superstar in the making.'
While Simon told her: 'It was just, it wasn't a 10, it was an 11 in my opinion. If it wasn't for people like you, I wouldn't bother making this show.
'And you have to wonder who were these idiots you auditioned for that didn't give you the break before, they must be did. The only people you need to trust is the audience, the audience always get it right.'
Christmas won a standing ovation after performing her own version of Tomorrow from hit musical Annie - a song Simon admitted to hating until her performance won him over - during her audition on April 20.
The performance left its mark on Amanda, who instantly picked her as a Golden Buzzer act.
'What struck me so much about you is how naturally funny, how warm and how brilliant your presence was the moment you walked on the stage,' she told her.
'And tonight you have done even better, I just cannot believe your capacity and your fire and your strength.'
