ABC will broadcast a special report of never-heard-before interviews with Jacqueline Kennedy on September 13, all reportedly made in the months after her husband's assassination and sealed in a vault since November 22, 1963.
In the sensational tapes the former first lady speaks candidly with historian Arthur Schlesinger, Jr about her life in the White House with her husband, President John F. Kennedy.
Previous reports have suggested the tapes may contain explosive content, including the details of JFK's affair with a White House intern and Jacqueline's theory that Lyndon B Johnson and a group of Texas tycoons were involved in the assassination of her husband - but ABC will neither confirm or deny these claims.
After the former First Lady conducted these interviews in the months after her husband's death, she then refused to ever publicly discuss the details of that period in her life with anyone else.
The two hour long prime time report is also expected to feature Diane Sawyer's recent interview with the couple's daughter, Caroline Kennedy.
Currently ABC are denying rumors that Kennedy's tapes will reveal her belief that the then vice president - with help from businessmen in the South - planned the Dallas shooting, with the gunman Lee Harvey Oswald being only one part of a wider conspiracy.

Kennedy ordered the tapes should not be released until 50 years after her death, reportedly fearing that her revelations might make her family targets for revenge. She died 17 years ago, aged 64, and now her daughter Caroline Kennedy has agreed to release the recordings early.
The Daily Mail reported this week that Caroline, 53, agreed to the early release of the tapes in exchange for ABC dropping a $20 million drama series about the family.
Meanwhile a spokesman for ABC told the press that dramatic claims about the content of the tapes were 'erroneous.'
"The actual content of the tapes provide unique and important insight into our recent past from one of the most fascinating and influential First Ladies in American history," the spokesperson said."ABC isn't releasing any content from those tapes until mid-September, at which time it will be clear how off base these reports are."
