For years, Prince Harry and Prince William didn’t speak about the death of their mother, Princess Diana.
Harry made the admittance himself at a BBQ event last week for the mental health charity campaign 'Heads Together', where he spoke with several special guests including retired footballer Rio Ferdinand.
Speaking to Ferdinand - who lost his wife Rebecca Ellison from cancer last year - about his mother's passing, Harry said: "You know, I really regret not ever talking about it."
While the reason behind his silence over the years is not known, several insiders have since speculated why the Prince might have kept quiet.
“For a long time, they worried, and those around them worried, too, that whatever they said about their mother could be misinterpreted as somehow being critical of the Prince of Wales,” an aide said.
“The whole Diana subject was tricky, and their sensitivity about saying anything was noticeable.
“They were often upset when their mother's name cropped up, especially when books about her came out, but there was this reluctance to say or do much.”
Prince Harry and Prince William also reportedly stayed quiet about their mother for the sake of Camilla, the Duchess of Cornwall, who was their father’s first true love, and remains by his side to this day.
While it’s unclear why Harry has chosen to speak out about Diana now, what is certain is that he seems determined to encourage other kids going through a hard time to express their feelings.
"It's OK to suffer, but as long as you talk about it. It is not a weakness. Weakness is having a problem and not recognising it and not solving that problem,” he told the BBC.
"A lot of people think if you've got a job, if you've got financial security, if you've got a family, you've got a house, all that sort of stuff, everyone seems to think that is all you need and you are absolutely fine to deal with stuff."
Harry - who set up 'Heads Together' with his brother Prince William and his wife, the Duchess of Cambridge, has been compared to Princess Diana over the last few years for his penchant for charity.
“Like his mother, he has an emotional intelligence, is tactile, too, and, like her, connects easily with people,” a source told BBC. “He is not afraid to show his humanity. Shining a light onto forgotten children around the world seems a very natural thing for him to do.”
