In an interview that is certain to appall as many people as it fascinates, Casey Anthony's parents will finally speak out to Dr. Phil about what really happened to their granddaughter.
In the hard hitting interview they are also expected to reveal new information that may have changed the outcome of the case, a report in The Daily Mail has claimed.
George and Cindy Anthony's first interview since the not guilty verdict in their daughters trial was conducted by Dr. Phil and will be broadcast on September 12.
In a new promotional clip for the interview Dr. Phil takes a combative tone with the grandparents of Caylee Anthony.
'I want you to answer my questions, the truth once and for all,' Dr. Phil tells the two grandparents in the video.
Throughout the 30-second clip George and Cindy Anthony are not heard speaking, but a Daily Mail source has claimed they will reveal new information about the case that riveted the nation.
'America's never heard of this explanation before. Why have you sat on this information?' Dr Phil asks, adding: 'You know the truth don't you?'
Throughout the investigation into Caylee's death, Mr and Mrs Anthony maintained their daughter's innocence. However attitudes changed on the first day of their daughter's murder trial, when the defense claimed that Caylee drowned in the Anthony's pool and that George Anthony had molested her. The defense also claimed that George had persuaded his daughter to cover up the accident.
Unsurprisingly, the Anthonys have only had limited contact with their daughter since her release from prison, and they have met in person. It's believed that they are now irreparably estranged.
Meanwhile Casey Anthony is currently serving one year's probation in Florida for a check fraud case unrelated to her murder trial. Her currents whereabout are unknown.
