Prince Harry is getting candid about his mother's tragic death.

“I knew there would always be a gaping hole that could never be filled,” the 31-year-old royal said of losing his mom, Princess Diana, during a speech at the Mamohato Children’s Centre in Lesotho, Africa on Thursday, Nov. 26.

Following his appearance at the Mamohato Children’s Centre—an African orphanage built by Harry's charity, Sentebale—the Prince of Wales admitted losing a parent at such a young age has given him a personal connection to orphaned children.

“The children at [Mamohato Children’s Centre] were far younger than me, and of course, their situation was a great deal more challenging than my own,” Harry said, according to Us Weekly. “Nonetheless, we shared a similar feeling of loss, having a loved one—in my case a parent—snatched away so suddenly.”
