A set of previously-unheard audio interviews with former First Lady Jacqueline Kennedy are been released to the public this week in tandem with a new book -- Jacqueline Kennedy: Historic Conversations on Life with John F. Kennedy -- and Monday morning, ABC News played parts of the tapes.

The interviews -- which were sealed by the Kennedy Library prior to now -- were recorded with White House aide/Kennedy family friend Arthur M. Schlesinger Jr. just four months after former President John F. Kennedy's November 22, 1963 assassination.

In one sequence of the never-heard-before tapes, Jacqueline recalls how she pleaded with her late husband that she wanted to stay by his side during the tense days of the Cuban missile crisis, with nuclear war a real and scary possibility.

Explosive tapes which Jackie Kennedy made following the assassination of her husband, revealing details of her private life with President John F Kennedy, may soon become public.

The former first lady is believed to have spoken candidly about her and her husband's extra-marital affairs and who she believed killed him in the secret audio tapes which she made with historian Arthur M Schlesinger Jr within months of JFK's November 23, 1963 assassination, according to The Daily Mail.

Schlesinger had been a Kennedy friend and confidant for many years, and following the assassination wrote the acclaimed book A Thousand Days: John F. Kennedy in the White House, which won him a Pulitzer Prize.

The UK newspaper reports Jackie spoke to Schlesinger of her suspicions that her husband had an affair with a 19-year-old White House intern, whose underwear she found in their bedroom. She also reportedly spoke of her own revenge affairs with actor William Holden and Fiat car mogul Gianni Agnelli, and of her belief that Vice President Lyndon Johnson and a group of Texas tycoons were behind her husband's murder.

The tapes are said to have been sealed in a vault at Kennedy Library in Boston.

Jackie, who later married Aristotle Onassis, died of cancer in 1994, and her daughter Caroline Kennedy has reportedly now decided to let the tapes be turned into a TV special.
