Is this the craziest thing we have heard all week?

Pippa Middleton has been accused of wearing a fake bum at the royal wedding!

Pippa’s bum was the talk of the day this time three years ago – much to the delight of her sister we can imagine. But now, it has all been called out as a lie.

Stephane Bern, a French expert on etiquette has called Pippa out on her famous bum, saying: “But of course she had a false bottom … I repeat it: She had a false bottom. You take her away from that and she has normal buttocks … It was an optical illusion. She knew there were a billion people watching. It was the moment to show it.”

Kate Middleton’s sister has already spoken about the attention she received on that famous day, saying that her dress fitted a “little too well”. She added: “recognition has it’s upside, it’s downside – and you may say – it’s backside.”

Well, at least she has a sense of humour about the whole thing. We wonder if she will have a similar sense of humour about this recent accusation? Somehow, we doubt it.

Pippa’s bum was so famous it had it’s own Facebook page – but could those billions of people really have been duped by a fake?

We’re not expecting a formal statement from Clarence House anytime soon.
