Prince Harry has given a rare candid interview about his mother, Princess Diana.
The 31-year-old prince told PEOPLE he was inspired by his mum, who passed away when Harry was just 12.
"All I want to do is make my mother incredibly proud," he confessed. "That's all I've ever wanted to do."
Princess Diana died in a car accident in 1997 at the age of 36, tragically leaving behind her two young boys, William and Harry.
During her life, Diana worked hard for charities and causes, such as HIV/AIDS, homelessness and leprosy.
Harry, who has followed his charitable pursuits to America, said the death of his mother left a "gaping hole" in his life, and in the lives of those whom she helped.
"When she died, there was a gaping hole, not just for us but also for a huge amount of people across the world," he said. "If I can try and fill a very small part of that, then job done. I will have to, in a good way, spend the rest of my life trying to fill that void as much as possible. And so will William."
Prince Harry is currently working on taking his Invictus Games to America. The sporting Olympic-like event is for veterans suffering from injury or illness.
