What's that famous maxim? She's wonderful to say hello to, and even better to watch leave. But it looks like Americans hoping to meet Pippa Middleton, or her infamous bum, will have to wait a little longer. The British socialite has backed out of promoting her book in the U.S., the new party-planning guide, "Celebrate."

Middleton, the younger sister of the future queen of England, received a six-figure paycheck to write "Celebrate: A Year of Festivities for Families and Friends," a 400-page, lavishly illustrated how to book about creating perfect British parties. But don't expect to meet her on the upcoming tour for her book. Viking Press, Middleton's publisher has announced Her Royal Hotness will not be along for the ride.

Of course, the 29-year-old likely doesn't need to stoke publicity for her new book. Excerpts have appeared in the Oct. 28 issue of Parade Magazine, which featured, "tricks and treats for a royally spooky (Halloween) holiday." Not to mention her name is never far from scandal.

The press's love affair with Middleton's behind began after photos emerged from the royal wedding of her carrying sister Kate's gown train from behind showing off her rear end in her stunning white dress. The socialite's bottom has three Facebook pages, and at least one formal website dedicated to it.

The royal bride also infamously destroyed search engines across the Internet for weeks with an influx of "Kate Middleton topless" searches after the she was snapped sunbathing nude by a tabloid.

Attending the press tour for "Celebrate" would only open up Middleton to questions regarding all of this, and possibly criticism, or ridicule.

"Celebrate: A Year of British Festivities for Families and Friends" is a 400-page "feel-good book" that contains practical tips on how to host British-themed parties, including recipes, crafts, and games.

"It's a bit startling to achieve global recognition before the age of 30, on account of your sister, your brother-in-law, and your bottom," Middleton writes in the first sentence of the book's introduction.

The book is rumoured to be thoroughly British in colour - see what we did there? - so, xenophobic Americans, or those afraid of haggis paired with a hearty Shepard's pie might do better avoiding the book.

Boxing Day, Burns Night, Guy Fawkes Day and All Hallows' Feast are all detailed with careful fascination like so many cricket matches ... right?

Advice on picnics, camping, cocktails, and beach games is also included. Middleton, attempting to whimsically offer something for everyone, even includes games for kids, songs, poetry, a how-to on home preservation, and even a guide to star-gazing.

"It is a useful and practical journey into British-themed occasions," Pippa writes, based on her experience working for the Middleton family's online party business, Party Pieces, and for a London events-planning outfit, Table Talk.

While the book is more how-to than tell-all, Middleton does offer anecdotes about her favorite parties growing up in the Middleton household in Bucklebury, Berkshire.

"I know many of you will have picked up this book out of nothing more than curiosity," she writes, adding that it's strange to have seen so much written about her "when I have done little to paint a picture of myself. This is my first chance to do that and I've enjoyed every minute of it."

"Celebrate" is available now.
