Pippa Middleton admits in a new book that she is still somewhat mystified by all the fuss over her bottom.
After shooting to straight to fame thanks to her bottom's feature role at her sister's wedding to Prince William, Middleton says she is still coming to terms with her new life.
The 29-year-old made the confession in a new book all about party planning and how to host the perfect bash.
The Daily Telegraph quoted her as saying she was struggling with her celebrity - and the focus on her figure.
In the book, she writes: "It is a bit startling to achieve global recognition (if that's the right word) before the age of 30, on account of your sister, your brother-in-law and your bottom.
"One day, I might be able to make sense of this."
Middleton added that while she has had wonderful opportunities as a result of the marriage of her sister, she was still just a normal person trying to build a career.
Publisher Penguin was said to have paid her an advance of about £400,000.
Middle said the book was based on her experience in her family's party business and work in an events company.
She said that Celebrate: A Year of British Festivities for Families and Friends is a ''feel-good book'' with practical tips on how to host British-themed parties, including recipes, crafts and games.
Middleton holds no royal title, but her life has been subject to intense scrutiny since she captured attention at her sister's wedding with a close-fitting maid of honour dress.
The picture editor at the Daily Mail, Paul Silva, recently said that up to 400 paparazzi shots of her cross his desk every day.
Britain's media often characterize her as the party-loving, more vivacious contrast to the elegant and subdued Duchess.
