The photographer caught up in the Demi Moore airbrush scandal has offered up a $5,000 (£3,125) wager if the actress can prove the picture she posted online is the "original".
Moore was left fuming after critics claimed images of her from a new U.S. magazine photoshoot were drastically altered.
The Ghost star appears on the December (09) cover of America's W magazine in a revealing olive green dress, and online gossip has been rife that the photographs were heavily edited to slim down her hips.
Moore hit back at the rumours by posting the 'original' picture on her Twitter.com page, insisting the flawless photo never underwent any retouching. She wrote, "Here is the original image people, my hips were not touched. Don't let these people bulls**t you!"
But photographer Anthony Citrano is adamant Moore has not been completely honest with her fans, and he's offered to give $5,000 (£3,125) to the charity of her choice if she can prove the picture she posted is indeed untouched.
He tells celebrity blogger Perez Hilton, "I feel bad that Demi is on defence - she should not have to defend other people's mistakes; W Magazine should be addressing this rather than her.
"Having said that, she did raise the stakes considerably yesterday by posting what she claims is the original unretouched shot, along with the accusation that 'these people' (presumably me) are 'bullsh**ting'.
"Well, whether or not her hip was botched, I do not believe for a moment that the image Demi posted yesterday is the original shot.
"If she's aware of that - and I expect she is - it's irresponsible (and silly) of her to make that assertion. So, I'll see her move and raise her $5,000: if the shot she posted yesterday is really the unretouched original, I will donate $5,000 to a charity of her choosing.
"Let's see who's 'bulls**tting', shall we?"
