John F. Kennedy and Jackie Kennedy married in 1953.

“It was a marriage of its time.

At the end of the day, Jack came back to Jackie and that was it.

They loved each other,” a family friend said.

And there is certainly evidence that Monroe and Robert met at least once.

He is very intelligent, and besides all that, he’s got a terrific sense of humor.

I think you would like him … [H]e isn’t a bad dancer either."

And few can better attest to this than Diana de Vegh, another of JFK’s alleged mistresses.

De Vegh noted that after one of these events, JFK brought her back to his Boston apartment.

“In this apartment, something different.

He was leaning toward me, with such a sincere gaze.

Yes, I knew how he felt about me.

How could I doubt this moment of such profound connection?

This was love, for sure.

And … now, it was sex, for sure,” she said.

“He turned and kissed me tenderly, and my breath was taken away.

Von Post’s musings aren’t the only evidence of the romance between her and JFK.

The former president also wrote letters to von Post, which went up for auction in 2021.

“If you don’t marry come over as I should like to see you.

I had a wonderful time last summer with you.

Both ladies have since reportedly confirmed that they indeed engaged in extramarital affairs with JFK.

As noted, Jackie Kennedy reportedly knew of her husband’s alleged affairs.

Meyer and Jackie were friends, and Meyer allegedly had an affair with JFK.

Meyer was murdered, and to this day, the case remains unsolved.

… No gun was ever found,” Meyer’s biographer wrote, as reported byPeople.

Crump Jr. was later exonerated of the crime.

That all changed when Jackie hired Pamela Turnure Timmins, a woman Jackie admired.

I know she will do it correctly, so we don’t even communicate for weeks on end.”

There were reports that Timmins and JFK were having an affair.

And I can’t really adequately describe the electric feeling that was in that room."

Even a former Kennedy aide denied knowing her after JFK had died.

Exner and JFK’s affair allegedly lasted years.

“I was 26 and in love,” Exner said.

“Was I supposed to have better sense and more judgment than the president of the United States?”

“I think he did take advantage I was so young,” she said.

Alford remained honest with herself and her readers about her entire relationship with JFK.

He was magnetic," she said.

Marlene Dietrich had a brief affair with JFK

John F. Kennedy knew some very famous people.

The report claimed that JFK had invited to Dietrich to visit the White House.

And then he went to sleep.

I looked at my watch, and it was 6:50," Dietrich said of their tryst.

Dietrich assured him she had not.

Arvad rubbed shoulders with some of the most famous men in history.

But the FBI didn’t know that at the time.

They were desperate to find something.

And the less they found, the more they were convinced [Arvad] was hiding stuff."

Arvad, a writer by trade, also met with Adolf Hitler.

“You immediately like him …

The eyes, showing a kind heart, stare right at you.

And then there was JFK.

The politician allegedly didn’t reciprocate those feelings.

Then he turned and left to catch his plane,” Tierney said in her book.

“I always felt that I was an artist, entertaining.

I was at ease being a stripper.

Whatever it is she did, Starr allegedly grabbed John F. Kennedy’s attention.

Starr wrote a book about her life and times, but she claims it omitted some salacious information.

Jackie didn’t stay, but the two politicians did.

“So I took JFK’s hand and led him into another room.

He led me right into a large closet.”

All the while, she was engaged to the governor of Louisiana at the time, Earl K. Long.

“I remember Audrey Hepburn, and I remember how the whole office was impressed when she walked in.

But it does seem like JFK was a busy guy.
