Prince Harry was still too young when Princess Diana passed away, but he inherited a number of the late Princess of Wales' mannerisms.

The Duke of Sussex turned 34 years old today. As a tribute to the prince and his mom, Princess Diana, who gave birth to him, here's a list of their striking similarities from their mannerism to commitment in certain charities.

Prince Harry is a rebel like Princess Diana

The People's Princess was branded as a royal rebel because she broke a number of royal protocols. The duke did the same especially before he met Meghan Markle.

For instance, he made headlines after playing a game of strip billiards. His naked photos landed on the cover pages of several tabloids. Prince Harry was also caught cheating at school. In addition, he got drunk and fell into a pool.

Princess Harry inherits Princess Diana's aura

According to Elton John, Prince Harry inherited Princess Diana's "incredible gift" of connecting with people.

"Harry has inherited his mother's ability to walk into a room and make people, of any caste or any status in life, feel equal," John said. "That is an incredible gift. I've been around for 71 years and Princesses Diana was one of the few people in my life who could do that."

"Harry has inherited that gift. He knows he has that gift," John continued. "And that why he wants to do more with the AIDS community, the Commonwealth, and the young."

Prince Harry and Princess Diana share the same mannerism

Prince Harry bit his lip when he saw Meghan Markle at the altar on their wedding day. According to royal experts, this is micro-expression that Princess Diana also does. Good Housekeeping shared a number of photos of the Princess of Wales biting her lips to support its claim.

Both are dedicated to helping Africa

Princess Diana made several trips to the continent. She met Nelson Mandela and teamed up with Red Cross to help amputees and end the stigma of HIV/AIDS.

Prince Harry also considers Africa his second home. In fact, he has visited the continent multiple times with his wife, Markle.

Their charity efforts are remarkable

Princess Diana and Prince Harry are both involved in a number of charities. The late Princess of Wales was the patron of The Leprosy Mission and Centrepoint. She also did countless hospital visits to comfort those who are suffering.

Meanwhile, Prince Harry is the patron of the Invictus Games Foundation. The prince is dedicated to comforting and helping injured veterans.
