Princess Diana is heard discussing her thoughts and feelings about her marriage to King Charles in previously unheard tapes.
The late royal secretly recorded the clips in the 90s to send to author Andrew Morton, who wrote the infamous book Diana: Her True Story.
In the recordings, Diana can be heard discussing her husband, her sons and the troubled relationship she had with her stepmother Raine Spencer.
All of the clips are set to be released in a new documentary, scheduled to be aired next year, but ABC have obtained some of the recordings.
Speaking about her wedding day she said: “It was grown up. Here’s Diana, a kindergarten teacher. I mean the whole thing was ridiculous.”
She also spoke at length about her strained relationship with her stepmother, who married Diana’s father John in 1976 after her mother Frances Shand Kydd left.
She explained: “I was so angry. I said I hate you so much. If you only knew how much we all hated you for what you’ve done. You ruined the house.
“You spent daddy’s money. I have said everything I possibly could. Raine said you have no idea how much pain your mother put your father through.
“I said pain Raine? It’s one word you don’t even know how to relate to. In my job I see people suffer like you never see. You call that pain? I said you’ve got a lot to learn. I remember really going for her gullet.”
In the tapes Diana also airs her frustration that Charles wouldn’t speak to Raine.
She said: “At Harry’s christening Charles went up to mummy and said: ‘We’re so disappointed, we wanted a girl’ and mummy snapped his head off and said you should realise you are lucky to have a child that’s normal.
“Ever since that day, the shutters have come down. That’s what he does when he gets somebody answering back at him.”
