Pippa Middleton is said to be close to signing a book deal on how to be the perfect party hostess. The Duchess of Cambridges sister was launched into the spotlight after her appearance at the royal wedding, and now literary agent David Godwin is in talks about a book, which would be certain to become a lucrative deal. The book is an obvious choice for the 28-year-old socialite, whose family own a party planning service. It is reported Miss Middleton has had two meetings with publishing executives at HarperCollins and has met with several other publishing houses. There are predictions that she could make more than 1m from royalties and the sale of international rights and spin-off projects. TG
