RAGE AT AUTHOR AFTER CLAIM: BILL RAPED HILLARY, CONCEIVED CHELSEA

Now that's what I call a headline. (Thanks to Drudge, the king.)

Senator Hillary Rodham Clinton turned furious and considered legal action after learning bestselling author Ed Klein would allege in a new book: Bill Clinton raped her -- resulting in the conception of daughter Chelsea Clinton!

"[Author] Klein is going to rot in hell for this," a well-placed source close to Hillary said over the weekend.

Here's the real news - someone close to the Clintons actually believes in Hell.

The explosive charge comes in THE TRUTH ABOUT HILLARY: WHAT SHE KNEW, WHEN SHE KNEW IT, AND HOW FAR SHE'LL GO TO BECOME PRESIDENT -- set for release next week. [The book ranked #198 on AMAZON.COM's hourly sale chart late Sunday.]

"I'm going back to my cottage to rape my wife," Klein quotes Bill Clinton as saying during a Bermuda getaway in 1979.

Once a class act, always a class act, Mr. C.

Klein source claims Bill later learned Hillary was pregnant reading about it in the ARKANSAS GAZETTE.

"The fact that his wife didn't tell him that she was pregnant before she told a reporter doesn't seem to phase him one bit, because he says, 'Do you know what night that happened?""'No,' I say. 'When?" "'It was Bermuda,' he says, 'And you were there!'"

The rape claim is just the beginning of Klein's alleged revelations, the DRUDGE REPORT can reveal.

TRUTH ABOUT HILLARY marks the most aggressive attempt yet to investigate Hillary.

The former first lady turned senator fumed as a close aide offered details of the book, an insider explains.

"Mrs. Clinton told me she would considering suing him for outright libel," the top Hillary source explains.

"This is the right wing attack machine on crack!"

But Hillary and her camp may have a hard time typecasting Ed Klein as a Clinton-crazed right-winger. Klein is the former foreign editor of NEWSWEEK and former editor in chief of the NEW YORK TIMES MAGAZINE. He is a frequent contributor to VANITY FAIR and PARADE.
