Pippa Middleton and other published authors

Pippa Middleton hopes to emerge from her sister Kate Middleton's shadow with the release of her first book, Celebrate. Unfortunately it's not a tell-all tome about life with Prince William for a brother-in-law, it's a helpful guide on how to plan the perfect party. Pippa has worked in her parents' party planning business for years - and she even organised Kate's hen do before the royal wedding - so she's more than qualified to give advice on kids' parties, games and recipes.

It's the first time the world will get to know the real Pippa Middleton for what she does best, rather than just for her shapely behind. No wonder the pre-sales are going through the roof!

Of course, she's not the first celebrity to have turned her hand to writing, or to have used their name to boost sales of a book. Click through the gallery for more actors/singers turned authors...
