Posh books battle it out

A publishing battle is brewing over two "revealing" new books about Posh Spice Victoria Beckham.

The star is due to publish her own autobiography, Learning to Fly, on 13 September.

But an unauthorised biography, Victoria's Secrets, aims to spill the beans on the "real" Posh and claims that single-minded ambition took her to the top.

The book is written by Virginia Blackburn and is also due for September publication.

Victoria's Secrets relies on interviews with former dance teachers, friends and members of Posh's former band Persuasion and portrays the singer as determined and driven, with a "passion for fame".

According to Beckham's own publishers her autobiography is about "the reality of fame".

They said it is to be "about what it's like to be one half of the most watched couple in Britain and how it feels to be the target of so much adoration and envy".

"Victoria sets the record straight about the controversies that have surrounded her, including the truth behind the beginnings of the Spice Girls, her wedding and her health," the publishers added.

Victoria Beckham now pursues a solo career

Last year Posh and her husband, Manchester United footballer David Beckham attempted to block the publication of an unauthorised biography by Andrew Morton.

The couple failed in their bid and Posh & Becks appeared in the shops, chronicling their rise to fame from their youth to the birth of their son, Brooklyn.

Morton is the author of previously revealing best-selling biographies Diana: Her True Story and Monica's Story.

Morton used a series of in-depth interviews with media analysts to relate a story of two young people struggling to lead ordinary lives, obsessed with their own privacy.

David was depicted as a docile house-husband, happy to look after Brooklyn and do the housework.

Victoria however was described as reluctant to watch her husband play football.

The book also suggested that Victoria has had cosmetic surgery and that she was upset after the Spice Girls appeared on the Brits.

In a retaliatory move, Victoria announced she would publish her autobiography based on her diaries for the past couple of years.

"I thought it was about time to set the record straight," she said at the time.
