Pippa Middleton is turning her attention to writing, having signed a deal to pen a book about hosting the perfect party, a UK newspaper says.
The Duchess of Cambridge's younger sister is believed to be banking a US$400,000 (NZ $539,000) cheque from publishers Penguin, The Mail on Sunday reported.
The 28-year-old finalised the deal last week after a bidding war between HarperCollins, Cornerstone and the successful Penguin.
"She had to deliver a synopsis that was sent to a number of publishers under a strict confidentiality agreement," a friend of Pippa's told The Mail.
"There were some serious offers, but Penguin stumped up the most cash.
"It will be about entertaining and how to throw the perfect party. It's not just about being the perfect hostess - it will also include recipes and information about how to host different types of events."
The brunette, who attracted global attention for her role as bridesmaid during sister Catherine's marriage to Prince William, sought royal approval before signing the deal, keen not to be seen as cashing in on her family connections.
"Kate thinks it's a brilliant idea," the friend said.
