Pippa Middleton has written this week’s Spectator diary, in which she takes on her critics directly:

‘I have been much teased for my book, Celebrate. Lots of journalists are saying that my advice is glaringly obvious… It’s all good fun, I know, and I realise that authors ought to take criticism on the chin. But in my defence, let me say this: Celebrate is meant to be a guide to party planning and, as such, it has to cover the basics. If I were to write a cookery book, for instance, I would be compelled to say that, to make an omelette, you have to break at least one egg.’

She really doesn't get it, does she?
