Former President Bill Clinton has a well-known reputation as a ladies' man, skirt-chaser and wayward husband. But was he so bold as to hit on a considerably older former first lady?

A new book claims Clinton attempted to put the moves on Jacqueline Kennedy Onassis while visiting her at her Fifth Avenue apartment in New York. According to "Bill & Hillary: So This Is That Thing Called Love" by Darwin Porter and Danforth Prince, which is scheduled for release later this month, the former first lady told her friend Katharine Graham, the former Washington Post publisher: "We almost indulged in a wrestling match. It was most embarrassing. I mean, I was flattered that I turned him on so much at my age, but Bill was just like Jack in the sense that neither of them wanted to take 'no' for an answer."

Kennedy donated to Clinton's first presidential campaign before she died at the age of 64 in 1994. He was in his late 40s at the time.

A representative of Hillary Clinton's 2016 presidential campaign shrugged off the allegations, telling the Daily Mail Sunday: "[Is it] possible to quote me laughing at the sheer absurdity of this story?"

The book also claims Hillary once demanded her husband be tested for HIV, since “he favored unprotected sex.” The former first family was thrilled when the results were negative, the book alleges.

An excerpt from the book reads: "One night on Martha’s Vineyard, Hillary had a candid talk with a former first lady, Jackie Kennedy Onassis.

"'Bill is a charismatic politician, but also deeply flawed. He has such charm you can always forgive him.'

"'I know of such men,' Jackie said, no doubt recalling her own years with another charismatic president.

"'You had Marilyn Monroe to compete with. I have a lesser light — Sharon Stone. Bill was hopelessly gone when she crossed her legs in 'Basic Instinct.'"
