One of the world's most eligible bachelors opened up about his desire to lose that title someday.

Prince Harry sat down with "Good Morning America" and talked about how much he loves children looks forward to having them of his own one day.

"I can't wait for the day. So, you know, it will be fantastic," the 31-year-old told Robin Roberts. "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."

In the meantime, the royal is happy to be the "fun uncle" to Prince William and Duchess Kate's adorable children, Prince George and Princess Charlotte.

"You've got to have fun in life. Otherwise, wow, imagine life without fun," Harry said. "You've got to be taken seriously, but I hope that I'm a fun uncle."

It's not all fun and games though, Prince Harry, who has served in the British Army for 10 years, including two tours in Afghanistan, is using his platform to raise awareness about the challenges of war heroes.

"When you look past the amputees, when you look past the burns, they're still the same people, and to be able to call them all my comrades, friends, we all share something," he said. "We share that uniform. We share the training. We share, in some cases, Afghanistan. It's very special."

Prince Harry candidly admitted it was a battle to come to terms with public life verse private persona.

"I suppose, inevitably, [I was] going to have to get to the stage where I was always going to be Prince Harry," he told the co-host. "Despite the fact that I always wanted to be Capt. Wales, treated the same and the same uniform as everybody else, that acceptance, the power that the name has."

The redheaded hunk visited GMA to promote the Invictus Games, which is Paralympic-style events for injured war veterans that will be held in May 2016 at Walt Disney World in Orlando, Fla., but it won't be Harry's first time visiting the park.

"It's one of my very, very happy memories, of going to Disney World with my mum," Harry recalled of his late mother. "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; and very, very happy memories," he said.

His mother's memory has driven the royal to commit to using his birthright for positive influence.

"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 explained.

"I hope that a lot of my mother's talents are shown in a lot of the work that I do," Prince Harry admitted.

The royal has also formed Sentebale, which is a charity that means "Forget Me Not," in honor of Princess Diana. It provides aid to African children in Lesotho, many of whom are struggling with AIDS. During his mother's lifetime, she was known to have changed the perception of the virus.

Prince Harry couldn't help but express his hope that his mother would be proud of him and his brother Prince William.

"I hope she's looking down, you know, with tears in her eyes, being incredibly proud of what we've established, I suppose," he said, adding, "I'm sure she's longing for me to have kids so she can be a grandmother again."

"I hope that everything we do privately and officially, that it makes her proud," Prince Harry admitted. "I think losing your mother at such a young age does end up shaping your life massively. Of course, it does, and now I find myself trying to be there and give advice to other people who are in similar positions."

The 31-year-old didn't leave out another inspirational woman in his life -- his grandmother, Queen Elizabeth, who will turn 90 in April 2016.

"Because of my time in the service, [I have] the utmost of respect, not just for her as a grandmother," Prince Harry said. "She was my boss for 10 years and I viewed her very much like that.

"Now it's really nice because I can go to her for advice and bend her ear with all the experiences she's had over the years," he said.
