Pippa Middleton: Surprised by fame for her 'bottom'

Pippa Middleton's party book, Celebrate: A Year of Festivities for Families and Friends, doesn't hit book stores until Oct. 30.

But according to an excerpt in You magazine, Duchess Kate's lil sis, 29, writes about being surprised by her new-found fame, focused on a certain body part, ever since last year's royal wedding.

"It is a bit startling to achieve global recognition before the age of 30 on account of your sister, your brother-in-law and your bottom," writes Pippa. You remember that Pippa's rear prompted a Facebook page and plastic surgery craze.

"One day, I might be able to make sense of this. In the meantime, I think it's fair to say that it has its upside and its downside. I certainly have opportunities many can only dream of, but in most ways I'm a typical girl in her twenties trying to forge a career and represent herself in what can sometimes seem rather strange circumstances."

Pippa goes on to say: "I am by nature an optimist, so I tend to concentrate on the advantages. One of the most attractive has been the chance to publish Celebrate. I've always loved to write, so it seemed natural to try to combine this passion along with my enjoyment for entertaining, an enthusiasm I hope to share with others."
