She's previously declared that she would consider posing naked for the right reasons, saying she'd do Playboy if the price was right.

But in the end Amanda Holden, 45, decided to use her first naked shoot to promote a good cause, posing without her clothes on a bed of cabbages for a new campaign poster for PETA.

The Britain's Got Talent Show stripped off for the un-retouched image, taken by photographer Trevor Leighton, to promote the animal rights charity's message to go vegetarian.

Amanda Holden decided to use her first naked shoot to promote a good cause, posing without her clothes on a bed of cabbages for a new campaign poster for PETA

Her long blonde hair spread out behind her, the mother-of-two looks completely at ease showing off her body.

She hopes the campaign will encourage others to embrace a vegetarian diet, which she credits for keeping her skin in great condition and her figure in check.

'For me, there are many benefits,' she revealed. 'My skin's always good. I never feel bloated.'

Amanda has been a strict vegetarian since the age of 13, but even before that she was never keen on eating meat.

'I don't really know what prompted it but my mum says that even when I was really little I would eat all the veggies off the plate, including broad beans,' she said.

'And I used to leave the meat or keep it stuffed in my mouth and spit it down the toilet secretly.

'When I was old enough to understand that meat was actually animals there was a point where I went: "No more".'

The animal lover urged people to consider how giving up meat can improve health as well as having a positive impact on the planet.

'Each person who goes vegetarian drastically reduces his or her carbon footprint and spares many animals every year immense suffering on factory farms, in abattoirs and on the decks of fishing boats,' she said.

'For anyone who thinks being vegetarian is tricky, it's rubbish. There are so many so many products you can buy - meat substitutes if that's what you want, vegetables, lentils, pulses, there are a million things you can cook and use.

She concluded: 'The best thing you can do for animals is just leave them off your plate.'

It's no surprise that Amanda was confident enough to flaunt her figure in the new PETA campaign, as she's known for her fondness for a daring red carpet gown.

Stepping out alongside her co-judges Alesha Dixon, Simon Cowell and David Walliams, the presenter stole the show in her daring ensemble.

Narrowly avoiding a wardrobe malfunction, the sheaths of material just about protected her modesty, but revealed more of her fantastic figure as she turned to the side.
