The 31-year-old royal opens up about his mother's legacy and having fun with Prince George and Princess Charlotte.
Prince Harry says Princess Diana would have loved being a grandmother.
The 31-year-old royal opened up about his late mother on Good Morning America, revealing he thinks she would have cherished her relationship with Prince William's children and his own future offspring.
"I hope she's looking down with tears in her eyes, being incredibly proud of what we've established, I suppose," Harry told GMA co-anchor Robin Roberts of his mom, who died when he was 12 years old. "I'm sure she's longing for me to have kids so she can be a grandmother again."

As for Harry, he says he "can't wait" for the day he starts a family of his own.
"It will be fantastic," he explained. "I've got a kid inside of me. I want to keep that. I adore kids. I enjoy everything that they bring to the party. They just say what they think."
Which is why he loves spending time with his niece and nephew, Prince George and Princess Charlotte, and Harry reveals what kind of uncle he is to them.
"You've got to have fun in life. Otherwise, wow, imagine life without fun," he said. "You’ve got to be taken seriously, but I hope that I’m a fun uncle."

Harry is currently promoting the Invictus Games, a sporting event for wounded armed services members and other vets, that will take place from May 8 to 12 at Walt Disney World's ESPN Wide World of Sports Complex. The location holds a special -- and very sweet -- place in his heart.
"It's one of my very, very happy memories, of going to Disney World with my mum," he recalled. “I went on ‘Space Mountain’ 14 times. I was like, 'This is absolutely fantastic. This is the best thing ever.' There's all sorts of places over the world where we were very lucky to have those moments with our mother -- very, very happy memories."
Now, the prince hopes that Diana's legacy lives on through the Games and his other charity work.
"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 concluded. "I hope that a lot of my mother's talents are shown in a lot of the work that I do."
