Shirley MacLaine: Marilyn Monroe had both Kennedy brothers in bed hours after she sang ‘Happy Birthday, Mr. President’

Shirley MacLaine says Marilyn Monroe went to bed with both John F. Kennedy and his brother Robert on the same night. 

The Oscar-winner, 90, makes the scandalous claim in her new coffee book, “The Wall of Life: Pictures and Stories from this Marvellous Lifetime,” 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 she attended an afterparty where she saw President Kennedy leave a bedroom with Monroe inside.

Shockingly, MacLaine asserts that Robert F. Kennedy — who was then serving as US Attorney General — entered the room immediately after, presumably to have sex with the “Some Like It Hot” star straight after his sibling did.

“In 1962, at the famous celebration for John F Kennedy’s 45th birthday 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,” MacLaine writes in her book.

“Afterward there was a private party at [Democrat finance chairman] Arthur Krim’s home… Jack Kennedy had just walked out of the bedroom behind me, and Bobby [Robert] Kennedy had just walked in. Marilyn was in the bedroom.”

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

In her new book, MacLaine also shares another photo implying both JFK and RFK had been up to no good.

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

MacLaine isn’t the first to allude to the Kennedy brothers both being embroiled with Monroe on the evening she sang “Happy Birthday, Mr. President.”

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

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

She alleged the actress arrived on stage “drunk and flush with the transgressive sex she’d just had with Bobby [Robert], her dress so tight she could hardly walk.”

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

The author wrote Jackie then gave her husband an “ultimatum.” She forbade him from seeing Monroe again, saying “she would divorce him — taking the children and costing him a second term [in the White House].”

According to Callahan, however, Monroe’s relationship with RFK continued.

RFK even allegedly visited Monroe the night she died at her home in Los Angeles: Aug. 4, 1962.

“The FBI and the CIA, Bobby and Jack discovered, had bugged Marilyn’s house and phone line without her knowledge… Bobby wasn’t leaving without the tape recordings,” she wrote.

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

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

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

“It was scary just how obvious he was being,” MacLaine claimed”. “He even figured out a way to try to stop me from leaving, but I had to get out of there.”
