George and Cindy Anthony
are about to break their silence.
's parents will appear on the season premiere of The Dr. Phil Show
on Sept. 12 – and the tough TV psychologist says he's not pulling any punches.
"Cindy and George have suffered a horrific loss with the untimely death of their granddaughter Caylee, and they have since endured an unprecedented public attack on their family," says Dr. Phil in a statement. "Have these attacks been warranted, or not? I looked them straight in the eye and asked some very tough questions. Nothing is off limits during this interview."
Since Casey Anthony was acquitted
, media outlets have been clamoring to score the first interview with the Anthonys. Dr. Phil explains that the interview is being done in return for a donation to Caylee's Fund, the Anthonys' charity.
"The couple will derive no income from Caylee's Fund," says Dr. Phil, explaining that the charity is "intending to focus on promoting processes to educate the public about – and advocate for grandparents' rights."
"We knew that we'd want to speak at some point and we figured there was no better place than with Dr. Phil," Cindy Anthony said in a statement. "We are hoping that by doing this interview, we will be able to help other people who may be experiencing struggles of their own. We certainly don’t want anyone to experience what we have these last three years."
