Cheating In Camelot? New Tell-All Claims Jackie Kennedy Had Affair WHILE First Lady -- PLUS: Was Bobby Kennedy Bisexual?

For years, Jackie Kennedy was the picture-perfect political wife, silently standing by while her husband, John F. Kennedy, allegedly had countless affairs right under her nose. But now, a new tell-all book claims that the Queen of Camelot had a secret affair of her own -- with ballet dancer Rudolf Nureyev! Only Globe magazine has a look at the exclusive claims from the new book, The Pink Triangle in their latest issue.

According to the Globe, the tell-all claims that Jackie flew Nureyev to Washington D.C., in 1963, and they soon "plunged into a secret love affair that lasted years."

As the magazine points out, they weren't always good at hiding it: The couple were caught photographed together in England in 1968, five years after President Kennedy's death, and that same year, Paris Match magazine claimed Nureyev had been overheard drunkenly boasting about his conquest.

According to Nureyev, she was just one of many Kennedys who fell for his charms. "I am the sexiest man alive," he once said. "Just ask Lee Radziwill. Just ask Jackie Kennedy. And if you don't believe me, ask Bobby and John-John Kennedy."

Indeed, the book claims, RFK and Nureyev were once spotted "kissing each other passionately in a phone booth" and that the ballet dancer and JFK Jr. were suspiciously close.
