10 Times Princess Diana Was the Most Badass Member of the British Royal Family

In Diana's infamous tell-all interview with BBC's Martin Bashir in 1995, she opened up about her bouts with depression after the birth of Prince William, as well as her history with eating disorders and self-harm. During the shocking confession, Diana admitted to "hurting her arms and legs," as a cry for help and that she would throw up her food as a way to cope with the pressures of her life. "It was a symptom of what was going on in my marriage," she said.

In another surprising move, Diana revealed that while she was struggling with depression after William's birth in 1982, the royal family turned the other way. "I felt like I was the first person ever in the royal family to openly cry and nobody knew what to do," she said, adding, "If you haven't seen it before, how do you support it?" Diana's bravery in admitting her struggles is likely one of the major reasons that both William and Harry work with mental health charities like Heads Together today.

Also during her BBC interview, Diana admitted that she didn't see herself being "queen of this country," but rather that she'd "like to be a queen of people's hearts." "I don't think many people would want me to be queen, and when I say many people, I mean the establishment that I'm married into," she went on. "They've decided that I'm a nonstarter, because I do things different, because I don't go by a rule book, because I lead from the heart and not the head. And albeit that's gotten me into trouble in my work, but someone's gotta go out there and love people."

Typically, children in the royal family were educated by a governess in the palace, but Diana made sure that Prince William would be the first heir to the British throne to be enrolled in public school as soon as he was of age. At 3 years old, William began attending nursery school, and when his own son George was just 2 1/2, he and wife Kate had him start at the Westacre Montessori School. William and Kate's 5-year-old daughter Charlotte and 6-year-old son George both attend Thomas's Battersea School, a private school in South London.

Diana attended a Vanity Fair dinner at London's Serpentine Gallery on June 29, 1994. For the event, she decided to wear what would become one of her most memorable and statement-making looks: a formfitting black off-the-shoulder number by Greek designer Christina Stambolian. Though the curve-hugging dress was actually made for Diana three years earlier, the princess "thought it was too daring."

So what made her change her mind? Diana knew that on the same night as the Serpentine event, her estranged husband Prince Charles would officially confess to his adulterous relationship with Camilla Parker Bowles in a televised documentary about his life and work. "She wanted to look a million dollars," said her former stylist, Anna Harvey. "And she did." The audacious look would go on to be dubbed "The Revenge Dress."

In June 1997, just two months before her death, Diana auctioned off 79 of her dresses and suits — including the dress she wore while dancing with John Travolta and her iconic Catherine Walker "Elvis Dress," pictured — to raise money for the Royal Marsden Hospital Cancer Fund and the AIDS Crisis Trust. The pieces were sold at Christie's auction houses in London and NYC, and according to Diana, it was all her 15-year-old son William's idea; in a handwritten note, Diana told bidders, "The inspiration for this wonderful sale comes from just one person; our son William."

Simone Simmons, an energy healer and one of Diana's spiritual advisers, described picking out the dresses to be sold with Diana in her book Diana: The Last Word. Apparently, Diana admitted that she had probably "tried too hard" to wear pieces that would impress the royal family, and quipped, "The Queen Mother had terrible taste, which is why I looked so awful."

Diana was known for getting up close and personal during her official appearances, and in April 1987, she became the first member of the British royal family to come in contact with a person suffering from HIV/AIDS without any protective gear. During a visit to Middlesex hospital AIDS ward, Diana shook the hand of a dying AIDS patient without wearing gloves. "HIV does not make people dangerous to know," she said in a speech. "You can shake their hands and give them a hug. Heaven knows they need it."
