The 45-year-old stripped off the cause and proving she really isn't camera shy, Amanda agreed for the image not to be re-touched. This is her completely au naturel...
Now that's body confident, right?!
In the shot, Amanda can be seen lying on a bed of green vegetables wearing absolutely nada. She ditched her clothes and strategically covered her modesty by posing on her side, flashing a huge smile for the camera.
Can you blame her? We'd so be beaming from ear-to-ear too if we looked as uh-mazing as she does.
For Amanda, who has been vegetarian since she was 13, fronting PETA's new campaign was a no-brainer for her and she admits she wasn't phased by really baring all for its promo shot.
She said: "My vegetarian lifestyle keeps my body trim, gives me loads of energy and makes me feel happy. So when PETA suggested not retouching this image, I said, 'Why not?' - the image is as natural as my lifestyle."
Amanda also gushed about the benefits of ditching meat from her diet, explaining her skin is always on top form and she "never feels bloated." She encouraged: "The best thing you can do for animals is to just leave them off your plate."
When she's not busy stripping off to support her vegetarian ideals, Amanda is busy on the panel of Britain's Got Talent.
Viewers are currently watching the show's live semi-finals play out onscreen, with BGT's grand final taking place this Saturday (28 May) on ITV.
This year marks Amanda's tenth year on the show, and while she had hinted it could be her last, it seems she has been persuaded to return to the talent competition's judging panel. Simon Cowell pretty much confirmed the return of Amanda and their fellow judges Alesha Dixon and David Walliams recently, claiming the current judges are "the best" the show is going to get.
So much so, that he had been tempted to recruit them for The X Factor!
Simon told Closer magazine: "We all like being on the show and that's what's most important... I hate to admit it, but David is very welcome back next year. The whole panel is!
"We actually even considered transferring them all on to X Factor, but their egos, if I suggested it, would be unbearable."
