Johan Eliasch was only cuckolded once (but for eleven years)

.. and it's probably true, because it's his ex-wife who's saying it. The Daily Mail has the story. I'm sorry for the long quote. Anyways, I suggest you go to the Daily Mail site directly. For those who can't wait, here goes: "It was over lunch at the exclusive Nobu restaurant in Mayfair that socialite and artist Amanda Eliasch dropped the bombshell: she told her husband Johan that she wanted a divorce. The multi-millionaire sportswear tycoon’s calm response – that he knew she was having an affair – almost had her choking on her sushi. She became hysterical and broke down in tears as he revealed that he had received an anonymous letter several months earlier, detailing her intimate relationship with Dr Jean-Louis Sebagh, the French plastic surgeon and Botox specialist, who numbers Madonna and Elle Macpherson among his famous clients.Johan, a close friend of Prince Andrew and once an environmental adviser to Gordon Brown, said they were being blackmailed and suggested Amanda do nothing about ending their marriage. But the love triangle soon made headlines, after a business associate of Dr Sebagh allegedly sold the story to a national newspaper.‘It was devastating to see it splashed everywhere,’ says Amanda. ‘I was sad for Johan. He’s a good person and didn’t deserve to have his name linked to a scandal that was entirely my fault.'".
... and repeating the story doesn't help either, I would say. Anyways, Johan gets 8 on the cuckold scale.
