Hillary Clinton once forced her horn dog hubby Bill to get anHIV test because she knew he preferred to do things au naturel withmultiple mistresses, according to an explosive new book,“Bill and Hillary: So This Is That Thing CalledLove,†the New York Post gossip section“Page Six” reported Sunday night.

Hillary got tested also. The Clintons drew a collective sigh ofrelief when they proved negative.

Authors Darwin Porter and Danforth Prince also claim that Billwaged his own little war on a woman named Jackie Kennedy Onassis ather Fifth Avenue apartment.

The former First Lady apparently met resistance when sherebuffed his advances. “We almost indulged in awrestling match. It was most embarrassing,†sheallegedly later told longtime Washington Post publisher KatherineGraham.

“I mean, I was flattered that I turned him onso much at my age, but Bill was just like Jack [Kennedy] in thesense that neither of them wanted to take‘no’ for an answer. Eversince that day, I prefer not to be alone withBill.â€

Graham, a notorious gossip, recounted the story to novelistTruman Capote who, quite a yenta himself, circulated itfurther.

An unnamed Clinton flack insisted to Page Six that Bill did nottry to have sex with that woman, Miss Onassis.

“[Is it] possible to quote me laughing at thesheer absurdity of this story?†the spokesperson askedrhetorically.

The book is scheduled for publication on December 21.

Don’t look for it under theClintons’ Christmas tree.
