Monica Lewinsky will publish her secret love letters to Bill Clinton

Monica Lewinsky is reportedly set to write a tell-all book about her affair with former US President Bill Clinton – including her intimate love letters to the ex-president and how he had an insatiable desire for threesomes.

Monica Lewinsky, 39, reportedly wants revenge on Bill Clinton, who she believes escaped unscathed while she has never been able to shake the disgrace of their Oval Office trysts.

Friends claim publishers are scrambling to get their hands on the book, and after holding meetings, the former White House intern has learned she could get as much a $12 million if she recounts every tawdry detail.

While she has not yet secured a book deal, her apparent attempts to cash in on the affair could rattle the Clinton marriage – and wreck Hillary’s bid for the presidency in 2016.

Speaking to the National Enquirer, her friends said the memoir could even spark further health problems for the former president, who has undergone heart surgeries.

“Her book could be more than just revenge, it could kill him!” a source said.

Her bids for a book deal will at least shake Bill Clinton – bringing him crashing down from the success he enjoyed after an energetic speech at the Democratic National Convention earlier this month.

“Monica has tried to move forward, but the nightmare of her affair with Bill still haunts her,” a friend told the National Enquirer.

“She’s facing 40 without a man in her life, and seething about the way her reputation was destroyed as the whole world watched.”

The book will also include never-before-seen love letters that Monica Lewinsky wrote to the president – some of which were so intimate she never sent them, another friend added.

They reportedly detail her love for Bill Clinton and how Monica Lewinsky, then just 22, could make him much happier than his wife, Hillary, who the president called a “cold fish”.

Bill Clinton also laughed about his nonexistent sex life with his wife – and said he thought he was not the only one looking for love outside their marriage.

“Monica can describe how Bill went on and on about his insatiable desire for three-way sex, orgies and the use of sex toys of all kinds,” the friend added.

As well as the heartbreak she suffered after her relationship with Bill Clinton, Monica Lewinsky also plans to detail the pain of ending a pregnancy at the height of her liaison with the president, the source said.

Monica Lewinsky was carrying a child fathered by a Pentagon employee called “Thomas”, she revealed in an earlier biography written by Andrew Morton.

“That void has never been filled,” said the friend.

She decided to develop the memoir after her sullied reputation meant she struggled to find work but realized she would get a generous offer for the book.

Monica Lewinsky is also writing it to get revenge on Bill Clinton, now 66, friends said.

“For years, Monica tried to protect Bill out of a misplaced sense of loyalty,” a source told the Enquirer.

“But she no longer feels that way, and her memoir is his worst nightmare.”

During her grand jury testimony against Bill Clinton in 1998, an immunity deal prevented her from exposing intimate details about their affair in the Morton expose that came out that year.

“But that agreement expired in 2001, and when Bill published his autobiography <<My Life>> three years later, Monica felt betrayed by him all over again,” said the source.

In the wake of the scandal, Monica Lewinsky became the centre of a political storm and gave a series of high-profile interviews.

But unable to escape the shake the reputation, she moved to England in 2005 where she earned her master’s degree and worked as a news correspondent for the UK’s Channel Five News.

Though it has been 14 years since Monica Lewinsky claimed she had nine sexual encounters with the president, her presence still looms in the life of Bill Clinton’s post-presidency and Hillary’s political career.

In what was an unfortunate and awkward schedule at the Democratic National Convention in North Carolina earlier this month, Monica Lewinsky’s former rabbi – who publicly condemned Bill Clinton during the sex scandal – gave the benediction minutes after the former President took the stage.

ABC News reported that the awkward pairing was likely overlooked by organizers because Rabbi David Wolpe is such a well-known figure in the Jewish community.

And in July, during a visit to Egypt as U.S. Secretary of State, Hillary Clinton was taunted by her husband’s affair by protesters as they chanted “Monica, Monica!”.
