  Casey Anthony (L) reacts as she listens to testimony about forensic evidence during her murder trial at the Orange County Courthouse in Orlando, Florida, June 10, 2011. Celebrity medical examiner Dr. Jan Garavaglia testified on Friday that bones scattered in woods near Casey Anthony's home were positively identified as those of her 2-year-old daughter Caylee. At right is Anthony's defense attorney Dorothy Clay Sims.

Casey Anthony claimed that her late daughter Caylee was conceived while she was date raped, according to her former psychiatrist.

Although the 25-year-old suspected her father George Anthony of fathering the 3-year-old, unsealed documents have revealed that Anthony also believed her daughter was conceived by rape, according to TMZ.

A Florida judge unsealed Dr. Jeff Danziger's deposition on Wednesday, which cites Anthony’s explosive allegation.

"Two beers, possibly given another drug. Woke up passed out ... Don't remember anything at a party, age 18. This is how she said she got pregnant," Danziger wrote regarding a 2010 interview with Anthony.

Danziger also reported that Anthony displayed no signs of mental illness after running medical tests.

Since Anthony was first reported missing in 2008 and through her murder trial, the public questioned who exactly was Caylee's father.

According to a number of sources, including Danziger, Anthony does not know despite a few suspects.

It was reported that her father George was ruled out after a DNA test confirmed he did not father Caylee.

Anthony, who despite her acquittal has been prosecuted for repeatedly lying, alleged that George had molested her before suggesting that her brother Lee also take a DNA test, to which he was cleared.

For a long time, Anthony has given conflicting explanations for who fathered Caylee, even once saying that she had a one-night-stand with a stranger.

The shocking revelation comes just as Anthony’s defense attorney Jose Baez allegedly quit and removed himself from her legal team.

It is unclear why Baez left, although sources are speculating that it relates to the recently "leaked" video diaries of Anthony, which have been posted on YouTube.

Chief Medical Examiner, Dr. Jan Garavaglia, who also examined Caylee's body, told talk show host Anderson Cooper that Caylee was murdered.

"It was a homicide … Without a doubt," Geravaglia recently told Anderson Cooper on his talk show.

Caylee's remains were found in a wooded area near the Anthony home in December 2008, and she was acquitted of murder in July 2011.
