Shirley MacLaine says Marilyn Monroe slept with John F. Kennedy and his brother Robert the same night.

The 90-year-old Oscar winner makes the outrageous claim in her new book about coffee: “The wall of life: images and stories of this wonderful life” which features a photograph from May 19, 1962, the night Monroe breathlessly sang “Happy Birthday, Mr. President” to JFK.

MacLaine was present at the event and says he attended an after-party where he saw President Kennedy leaving a room with Monroe inside.

Surprisingly, MacLaine claims that Robert F. Kennedy, then serving as Attorney General of the United States, entered the room immediately afterward, presumably to have sex with the “Some Like It Hot” star immediately after she did so. his brother.

“In 1962, at John F. Kennedy’s famous 45th birthday celebration at Madison Square Garden, Jimmy Durante and I performed for the president and the crowd, but what most people remember is Marilyn Monroe singing “Happy Birthday” to him. Birthday,” writes MacLaine. in his book.

“Afterwards there was a private party at (Democratic Finance Chairman) Arthur Krim’s house… Jack Kennedy had just come out of the bedroom behind me, and Bobby (Robert) Kennedy had just come in. Marilyn was in the bedroom.”

Monroe died just three months later. President Kennedy was assassinated late the following year.

In his new book, MacLaine also shares another photo that implies that both JFK and RFK were up to no good.

Beneath a snapshot taken in 1984, he writes: “Here I’m telling that story to Teddy Kennedy… and he’s laughing about how the boys got away with it all the time.”

MacLaine is not the first to allude to the Kennedy brothers getting involved with Monroe the night she sang “Happy Birthday, Mr. President.”

In his new book, “Don’t Ask: The Kennedys and the Women They Destroyed” Former Post columnist Maureen Callahan claims that 30 minutes before Marilyn sang for JFK, she had sex with Robert in her dressing room.

“They spent 15 minutes alone together,” Callahan writes in his book.

He alleged that the actress arrived on stage “drunk and blushing from the transgressive sex she had just had with Bobby (Robert), with her dress so tight she could barely walk.”

Callahan went on to allege that First Lady Jackie Kennedy was “furious” after the performance, leaving JFK “jawed” in the audience.

The author wrote that Jackie then gave her husband an “ultimatum.” She forbade him from seeing Monroe again, saying “she would divorce him, take the children and cost him a second term (in the White House).”

However, according to Callahan, Monroe’s relationship with RFK continued.

RFK even supposedly visited Monroe the night she died at her Los Angeles home: August 4, 1962.

“The FBI and CIA, Bobby and Jack discovered, had bugged Marilyn’s house and phone line without her knowledge…Bobby wouldn’t leave without the recordings,” he wrote.

Meanwhile, the Kennedys aren’t the only politicians MacLaine writes about in his new book.

The “Terms of Endearment” caption revealed a “scary” encounter she had with Donald Trump.

“Probably in the 1980s, I interacted with Donald Trump,” he wrote. “I was at a function and when he walked in, he saw me and straightened up. He started pulling at his tie and I realized immediately that in his mind he was starting to take off my clothes…and his.”

“It’s scary how obvious he’s being,” MacLaine said. “He even found a way to try to stop me from leaving, but I had to get out of there.”
