Prince Harry once made a heartbreaking confession about what his future children will mean for Princess Diana's legacy

AOL.com Editors

Princess Diana has been gone for almost 22 years, but her two sons have ensured her legacy lives on with their important charity work, their parenting style, and of course, through their own children. Prince William and Kate Middleton even named Princess Charlotte after his late mother: Her full name, Charlotte Elizabeth Diana, secures Diana's place in the British royal family.

The nearly four-year-old princess may not be the only Diana in the lineage. As the Duke and Duchess of Sussex prepare to welcome their first child, due late April or early May, many royal fans predict that if it's a girl, she will be named Diana. However, the name is not the only way that Prince Harry may honor his late mother, who tragically passed away when he was only 12. 

In 2016, the then 31-year-old royal revealed that his mother continues to impact "everything" he does, including in his future as a father, even two decades after her death. In a heartbreaking interview with ABC's Robin Roberts back in 2016, Harry maintained, "We will do everything we can to make sure that she's never forgotten and carry on all the special gifts, as such, that she had and that she portrayed while she was alive."

He continued:

"I hope she's looking down with tears in her eyes being incredibly proud of what we've established. I'm sure she's longing for me to have kids so she can be a grandmother again. I hope, once again, that everything we do privately and officially that it makes her proud." 

It was announced on Thursday that Harry and his wife Meghan will break precedent with the arrival of their first born and will celebrate "privately" as a family before announcing the news to the public, Kensington Palace revealed. The news comes a week after their arrival at their new home Frogmore Cottage, in Windsor.
