In an editorial to The Spectator, Pipa Middleton made fun of her own book addressing what critics called "far too basic" advice for the festive season.

If you can't beat them, join them. And that's exactly what Pippa Middleton is doing. After being criticized and laughed at for the "far too basic" advice in her new book "Celebrate: A Year of Festivities for Families and Friends", she has decided to join the foe and in an editorial to The Spectator has made fun of her own book.

"I have been much teased for my book. Lots of journalists are saying that my advice is glaringly obvious," she writes in the editorial. "A spoof Twitter account called @pippatips offers such pearls as 'Enjoy a glass of water by getting a clean glass and pouring in water from a tap or bottle.'"

"But in my defense, let me say this: Celebrate is meant to be a guide to party planning and, as such, it has to cover the basics," she adds. "If I were to write a cookery book, for instance, I would be compelled to say that, to make an omelet, you have to break at least one egg. Actually, that's not a bad idea. Or maybe I should write a sequel and call it Bottoms Up? Now that could be a bestseller."

Middleton added that she's finally prepared for her book signing. "I have finally perfected my signature," she writes, revealing that she takes pains to distance herself from her well-known surname. "It took hours of practicing...I decided early on just to write Pippa, not Middleton."

The festive season, Middleton reveals has always been a time for costumers and that's exactly what she'll be doing this year too.

"My father has developed a tradition of surprising us at some point by appearing in fancy dress. He buys a new costume each year and typically gets carried away," the Brit discloses of father Michael, who shares kids Kate, 30, Pippa, and James, 25, with wife Carole. "A couple of Christmases ago he appeared in an inflatable sumo outfit. It's endearing, really, and only quite embarrassing."
