According to the latest revelations in J. Randy Taraborrelli’s book “Jackie: Public, Private, Secret,” Jackie Kennedy found herself underwhelmed by Hollywood heartthrob Warren Beatty during a short-lived affair in 1978.

At that time, the former first lady was working as a book editor for Doubleday and was keen on securing top celebrities interested in penning their memoirs.

Taraborrelli’s extensively researched book, released this week, draws from nearly 25 years of investigation and numerous interviews with acquaintances, relatives, and romantic partners.

It also makes reference to undisclosed documents from the JFK Library, such as diaries and oral accounts.

Warren Beatty, known for his desire to portray the president in the 1963 film “PT 109,” had his sights set on the role before being passed over by John Kennedy in favor of Cliff Robertson.

By the time Jackie Kennedy crossed paths with the 41-year-old Beatty, he was a highly sought-after figure rumored to have been romantically involved with “almost every major female star in show business under the age of 50.”

Beatty’s biographer even suggested that he had been intimate with around 12,775 women prior to marrying Annette Bening in 1992 and committing to monogamy.

Despite finding Beatty intriguing, Kennedy only went on a few dates with him.

One of her staff members recounted a morning where Beatty casually conversed with Kennedy’s son, John F. Kennedy Jr., in her kitchen as if it were an everyday occurrence.

However, Kennedy grew disenchanted with Beatty, perceiving him as excessively self-absorbed.

According to reports, Beatty predominantly spoke about himself and his aspirations, neglecting to engage in meaningful conversations with Kennedy.

This lack of reciprocity led Kennedy to lose interest in the relationship.

Following their encounters, Kennedy purportedly found the physical aspect enjoyable initially but eventually tired of it.

When asked to evaluate Beatty’s bedroom prowess, she nonchalantly remarked that “Men can only do so much, anyway,” indicating her dissatisfaction.

Beatty, on the other hand, was reportedly hoping for a more engaging partner, considering Kennedy to be mundane compared to his expectations of a glamorous figure akin to Camelot’s queen.

Their differing lifestyles and priorities swiftly became apparent, leading to the demise of their brief liaison.

The final blow to their relationship occurred during a holiday gathering at Kennedy’s residence when Beatty unexpectedly arrived with his entourage, divulging private details about their intimacy to Kennedy’s stepbrother.

This breach of trust marked the end of their association.

As fate would have it, Kennedy later faced another disappointment involving a prominent figure.

In 1988, her son John Jr.’s involvement with Madonna, who was then married to Sean Penn, sparked disapproval from Kennedy due to her aversion to infidelity.

Despite speculation linking her disapproval to Monroe’s legacy, it was primarily Madonna’s marital status that troubled Kennedy.

Kennedy, known for her discerning nature, was unimpressed by Madonna’s persona and refused to engage with her, citing her distaste for promoting relationships she did not endorse.

The short-lived romance between John Jr. and Madonna concluded after six months, never evolving beyond a casual fling.

Ultimately, both Kennedy and Beatty’s encounters with these high-profile individuals underscored the challenges of navigating relationships in the public eye, emphasizing the importance of compatibility and shared values in fostering lasting connections.
