TV documentary makes shocking claim about Queen Elizabeth's reaction to Princess Diana's death

A new TV documentary, "Diana: 7 Days That Shook The Windsors," is revealing shocking details about what happened in the seven days after Princess Diana's death in August 1997.

Specifically, the documentary makes an astounding claim about Queen Elizabeth's reaction to Diana's fatal car crash in Paris. After hearing the news from her private secretary, the queen reportedly said she thought someone must have "greased the breaks" on the car.

The shocking claim echoes what was reported in a book by royal biographer Ingrid Seward just two years ago.

Queen Elizabeth's eyebrow-raising remark greatly highlights her complicated relationship with Princess Diana. A source revealed the queen saw Diana as a "misfit who didn't quite contribute to the things they did and what they wanted her to do in the family."

The royal family's aloofness towards Princess Diana affected her quite deeply. In a letter that she wrote to a close friend in 1991, Princess Diana revealed she felt "extremely isolated" from the royals at the time.

Since Diana's death, however, Queen Elizabeth has had quite a change of heart with how she feels about the mother of her grandsons:

"She would never say now that Diana hasn't contributed to the family. She sees how much Diana radiates out of William and Harry and the effect they have on ordinary people."

The documentary also delves deeper into how Princess Diana's sons, Prince William and Harry, handled her death. Harry, who was 12 at the time, was confused and wondered if his mother had really passed away.

"Prince Harry actually asked his father, 'Is it true Mummy's dead?" Tina Brown, the princess' biographer, said.

If you recall, the days following Diana's fatal car crash in Paris left the world in mourning. However, the royal family's initial reaction was to "do as they had always done," including going to church because it was a Sunday.

As Princess Diana's 20th death anniversary approaches, her sons have candidly opened up her death.

Prince William recently made some heartbreaking remarks about his late mother, who died when he was only 15 years old:

"I would like to have had her advice. I would love her to have met Catherine and to have seen the children grow up," William admitted to the publication. "It makes me sad that she won't, that they will never know her."
