The Beckhams are reportedly bracing themselves for the release of a book that threatens to put their marriage under the spotlight all over again.

The House of Beckham: Money, Sex and Power, by investigative journalist Tom Bower is set for release on June 20 and is set to uncover startling revelations about the couple. 

Speaking to The Mirror, Tom hinted that the book will explore David's alleged affairs, or any new allegations as he said: 'Those who want to know about Beckham's sex life won't be disappointed.'

While Tom has written a whole book on the couple, he didn't interview them face to face for the publication and instead spent two long sessions with a senior member of David's team. 

However aside from this, the author revealed the pair made it hard for him to research the book. 

David and Victoria Beckham are reportedly braced for the release of the latest tell-all book as journalist Tom Bower threatens to put their marriage in the spotlight AGAIN as he exposes the footballer's sex life in his latest release The House of Beckham: Money, Sex and Power

Speaking to The Mirror , Tom hinted that the book will explore David's alleged affairs, or any new allegations as he said: 'Those who want to know about Beckham's sex life won't be disappointed'

Tom explained: 'The Beckhams made sure that quite a lot of people wouldn't talk to me. But I did find enough people to talk to and got a lot of very interesting revelations. It was a book that surprised me. 

'We think we know everything. But in fact there is an enormous amount we don't know – which the public will find out.'

The former footballer, 48, touched on his so-called affair with Rebecca Loos in the Netflix documentary Beckham in November of last year. 

However, David made no direct reference to an affair and did not admit to any guilt - but did address the 'horrible' aftermath, which he claimed left him ‘feeling sick every day’. 

Rebecca, 46, who worked as David's assistant before going public with details of their alleged secret liaison in 2004, accused him of 'portraying himself as the victim' and shirking responsibility.

Tom didn't confirm whether his latest book will be damaging for the couple and instead suggested that the public will be allowed to decide what they think about the new information.  

HarperCollins are set to publish the new book, as they wrote on their site: 'Through extensive research, expert sourcing and interviews with insiders, Britain’s most celebrated investigative biographer, Tom Bower, has unearthed a succession of revelations that give surprising insight into the reality of ‘Brand Beckham’.
