Prince William and Prince Harry have both spent more of their lives without their mother, Princess Diana, than they ever got to spend with her.
After losing her in a tragic car crash in 1997, both princes mourned not only the woman they called "mum", but also one of their greatest royal role models.
Now 39 and 37 respectively, William and Harry have gone to great lengths to preserve their mother's memory and carry on her legacy in the 24 years since she died.
From charity work, to travel and of course, the beautiful tribute in Princess Charlotte and Lilibet's names, both of Diana's sons are keeping her memory very much alive despite the pain of her loss.
Speaking of his immeasurable grief, William once mused: "Initially, there is a sense of profound shock and disbelief that this could ever happen to you.
"Real grief often does not hit home until much later. For many it is a grief never entirely lost.
"Life is altered as you know it, and not a day goes past without you thinking about the one you have lost."
Meanwhile, Harry recalled walking in Diana's funeral procession in a 2021 mental health series with Oprah Winfrey.
"It was like I was outside of my body and just walking along doing what was expected of me," he said of the heartbreaking experience.
"[I was] showing one tenth of the emotion that everybody else was showing: This was my mum – you never even met her."
But the sons of the late Princess of Wales use their mother's memory to keep them going.
Diana's legacy of charity and huanitarian work has inspired their efforts across causes like mental health, homelessness, HIV and AIDS.
Not only that, both Harry and William have also established a number of their own projects and initiatives in her name over the years.
After all, as Harry said in 2021: "I've got a hell of a lot of my mum in me."
