Pippa Middleton Jokes About Sequel Called 'Bottoms Up', Offers Her Own @PippaTips

Pippa Middleton certainly has a lot to Celebrate.

Her debut novel might have flopped with the critics (Jilly Cooper was reportedly overheard saying "the people at Penguin are virtually slitting their wrists over it") but she still has a six figure advance - and an idea for a second tome.

Pippa Middleton took on a spoof Twitter account and offered her own @PippaTips

The Duchess of Cambridge's sister suggested a sequel to Celebrate: A Year Of British Festivities For Families And Friends in the latest edition of The Spectator magazine, published tomorrow.

"Maybe I should write a sequel and call it Bottoms Up?," she says. "Now that could be a bestseller."

Middleton admits she has been teased over the novel, but writes she is going to take criticism "on the chin."

"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."

Pippa - inspired by the fake @Pippatips account - announces her Christmas party tips, according to the The Spectator's steerpike.

1) Choose, if you can, a Christmas-themed menu. A turkey, for example, can be perfect for large gatherings.

2) Don’t not invite any members of staff, as this can cause offence.

3) Keep speeches brief and cheerful: Christmas is not a time to talk about redundancies.
