There are reports that secret recordings offer stunning revelations into Jackie Kennedy, in particular who she thought was involved in her husband's assassination.

Never-before-released audio recordings allegedly indicate that Jackie O believed then-Vice President Lyndon Johnson and a group of Texas businessmen were behind the Dallas shooting that left John F. Kennedy dead on Nov. 22, 1963, The Daily Mail reports.

The tapes -- which feature conversations between the first lady and historian Arthur Schlesinger Jr. shortly after Kennedy was assassinated by Lee Harvey Oswald -- also address extramarital affairs, including allegations of the president's involvement with a 19-year-old White House intern, and Jackie O's relations with actor William Holden and Fiat mogul Gianni Agnelli, according to the British tabloid.

ABC, which plans to air the tapes next month, has described the recordings as "explosive." But network officials deny that there's evidence of an LBJ-orchestrated hit on Kennedy.

"The tabloid reports about content of the tapes are total nonsense," a network spokesman told The New York Post. "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."

The recordings were supposed to remain in a vault at the Kennedy Library until 50 years after Jackie's death. But according to The Daily Mail, Caroline Kennedy gave the tapes to ABC just 17 years after her mother's death in a swap that would keep the network from airing its recent miniseries, "The Kennedys."
