Post-Gungate Pippa Middleton Ready to Pull the Trigger on Party-Planning Book This October

Duchess Kate's kid sister's book will include etiquette tips and wisdom she's accumulated throughout her career as a party planner

Pip, pip, hooray!

Pippa Middleton's Frenchman friend Viscount Arthur de Soultrait committed a major party foul over the weekend when, while playing host to Duchess Kate's kid sis, he allowed her to get snagged in a now-notorious fake-gun–waving incident.

Middleton, however, is a pro when it comes to throwing fabulous fêtes. She's such a great hostess, in fact, that she's now written a book on how to plan the perfect party.

In Celebrate, which its publisher tells USA Today will hit shelves in October, the 28-year-old Brit will share party-etiquette tips and tricks she's learned throughout her party-planning career.

Middleton, of course, has followed in the footsteps of her entrepreneurial parents. James and Carole Middleton founded Party Pieces, a mail-order party company, in 1987. Kate and Pippa's younger brother, 24-year-old James, also runs an upscale party-supplies outfit called the Cake Kit Company under the umbrella of the family business.

Kate might be a duchess, but Pippa will soon be a published author.
