John F. Kennedy’s flings with a teenage call girl in New York while he was President-elect connected the skirt-chasing politician to the notorious sex and spy Profumo scandal that brought the British government to the brink of collapse, a new book reveals.

Anthony Summers and Stephen Dorril detail in their new book, “The Secret Worlds of Stephen Ward,” how the British osteopath and sketch artist groomed numerous young women and introduced them to men in high society.

One of the women he met and sketched, play-for-pay girl Mariella Novotny, wound up going to New York as a prostitute. There, she was introduced to the Kennedy circle.

In a bombshell excerpt from Summers’ and Dorril’s book provided to Breaking Celebrity News, the authors expose how Novotny entered the Kennedys’ world of power and lust.

SHORTLY after her arrival in New York, Novotny wrote in her unpublished memoir, she had been squired to a series of lunches and parties. She was introduced as “the new import from swinging London.” The first lunch date, she recalled, had been at the venerable Luchow’s restaurant on East 14th Street, and “there I met Peter Lawford, one of the leaders of the Kennedy clan...Then, I was shot into the whirl of parties and was in­troduced to JFK, the President-elect. I heard several stories of his esca­pades and met some of the girls he had had affairs with.
