Amanda Holden collapsed into a fit of the giggles on Tuesday morning, as she took part in a very cheeky balloon modelling lesson.

The BGT judge, 53, was given a tutorial on how to sculpt a classic balloon dog on Heart Breakfast by professional balloon artist Lisa.

But as she attempted to pump up the balloon and twist it into shape, Amanda and her co-host Jason King couldn’t help making a number of naughty innuendos that caused them to fall about laughing.

Choosing a pink balloon to start with, the radio presenter began: ‘It’s a very cold balloon… Oh hello! Is this some kind of pump?’

Lisa then began talking her through each step while demonstrating the techniques, adding: ‘A little tip, don’t be too aggressive with your balloons because they will pop. They can feel your emotions. So no aggressive pumping.’

A baffled Amanda struggled to blow hers up, saying: ‘What? How far up do I need to?’ as Lisa kindly reᴀssured: ‘Maybe it’s a dodgy balloon, it’s not you!’

As Amanda finally got to grips with her pump, Jason told the listeners at home: ‘Alright we have a pink sausage shape.’

Amanda took the opportunity to quip: ‘Mines really bendy! It couldn’t happen to a better person.’

Lisa then instructed her to ‘burp’ the balloon slightly, releasing enough air that she could tie it off.

However, Amanda overdid it, declaring: ‘Oh no I’ve burped it too much!’ before adding: ‘I was always very good at winding my babies actually.’

Lisa then instructed: ‘Okay, so first of all you want to do the nose. So, decide how long you want your nose to be. I’m going to say like three fingers.’

Amanda was quick to joke: ‘That’s what I say when I do a measure of wine’ causing her and Jason to burst into hysterical laughter.

Lisa chuckled: ‘There we go, perfect! Do you ever stick to that?’ causing Amanda to reply: ‘Sometimes I say a fist, but we’ll see!

As they went through the last few steps, Amanda was left scratching her head over her dog’s tiny tail and ‘droopy nose’.

A baffled Amanda struggled to blow hers up, saying: ‘What? How far up do I need to?’ as Lisa kindly reᴀssured: ‘Maybe it’s a dodgy balloon, it’s not you!’

She then fell about laughing again as she said her tail was much more reminiscent of a part of her anatomy, joking: ‘Is that my tail? Look! That looks like my nipple! Oh my gosh!’

Lisa then revealed she had made a little balloon model of Amanda, with the TV personality immediately posing alongside the figure. She gushed: ‘Oh it’s me, look at my lips! This is epic.’

It comes the day after Amanda revealed on Monday’s Heart Breakfast how she worried for co-star Simon Cowell’s safety at a recent Britain’s Got Talent audition during a terrifying weapons stunt.

She explained that there was one ‘dangerous’ act that took place at the auditions over the weekend that involved the music mogul.

She recalled: ‘I’ve had BGT for days in wonderful Blackpool! But yes, I’m not going to lie, Simon Cowell decided to sort of… Well, he was involved in an act yesterday is all I’m going to say.

‘I mean so dangerous that I looked at the producers and just thought I didn’t know how sensible it was for him to be part of it.’

When her co-host Jason – who is standing in for Jamie Theakston – asked about the prospect of health and safety, Amanda confirmed there was none.

She said: ‘No, I mean, you know how like this world has got too much of the high vis and health and safety? It drives me nuts, but I was like “where were they?”

‘Yeah, and the only note Simon was given was “don’t move!”

‘Course he moved because he said he could feel the wind of this particular… I’m going to say weapon right by his head, and I mean, it was horrible to watch. 

‘Because also, the act involved a lot of food and a lot of crushing, so the stage was very slippy. 

‘So, with any safety measures that may have been put in place, there was risk there because of the sliding floor. 

‘I just don’t understand — it was mad! But anyway, bearing all of that in mind and, obviously, Simon’s bravery, he then had to go and get changed!’

The long-running talent series, which has discovered the likes of Susan Boyle, Diversity and last year was won by songstress Sydnie Christmas, will return to screens later this year.

Auditions for series 18 were cancelled back in October following the shock death of  Liam Payne earlier that month aged 31, after the former X Factor contestant fell from a third-floor H๏τel balcony in Argentina.

Amanda has appeared on the show since its inception in 2007, and recently let slip a huge spoiler for the new series on her radio show.

She said : ‘It’s BGT time. We’re doing the auditions in Blackpool and I’m all over the place. I’m doing Heart, I’m doing Blackpool, I’m doing everything! 

‘And yesterday, I mean it is a spoiler alert, I don’t know how much the producers care or if they’re even up listening. But yesterday we have never had so many birds on stage. 

‘Before you write in, I am going to say we had a pole dancing seagull, we had a man who played rubber chickens, and we had a man who dedicated an entire song to Bruno while sitting on a giant rooster!’
