A new book titled Jacqueline Kennedy Onassis, A Life Beyond Her Wildest Dreams blows the lid off the former First Lady’s private life, lending prescient insights into flings she purportedly carried on both before and after the assassination of her husband 50 years ago.

The book, which frequently quotes late Jackie O confidantes Gore Vidal and Truman Capote, drew obvious parallels between Jackie and her legendary ladies man husband, late Pres. John F. Kennedy.

“She and Jack both loved gossip and could go on talking endlessly about other people’s sex lives,” Vidal wrote, “but I always got the distinct impression that she was very interested in sex the same way that Jack was very interested in sex.”

“It was a game for them, and they both played it.”

The book, written by authors Darwin Porter and Danforth Prince, delves into many never-heard-before claims about the late fashion icon’s sex life, with detailed accounts of her flings with both of her late husband’s brothers, Ted and Bobby Kennedy; actors William Holden, Paul Newman, Marlon Brando, Warren Beatty, Gregory Peck; the chairman of the board himself, Frank Sinatra; and a number of other prominent men.

“Call it Brotherly Love,” Porter and Prince wrote. Three handsome Irish-American brothers were destined to fall in love with Jackie.

"In very different ways, she would love all three of them.”

According to the book, Jackie carried on concurrent flings with Bobby and Ted, the latter of whom had deep feelings for his sister-in-law.

Jackie’s confidante Nancy Dickerson said that “Jackie and Bobby were definitely having an affair.

Porter and Prince wrote that Ted once told JFK’s assistant David Powers that he’d “always been in love with Jackie, right from the beginning,” and that he wasn’t dissuaded by her link to both of his brothers.

“When Jack died, I knew she was seeing Bobby, too, but that didn’t stop me,” Ted told Powers, acceding to the tome. “Bobby couldn’t always be with her."

Capote said that Jackie once told him, "I'm in love with two men at the same time, both Bobby and Teddy."
