Princess Diana's adorable nickname for Prince William revealed

Princess Diana gave her eldest son, Prince William, a sweet nickname as a child.

• Princess Diana tragically died in a car crash in 1997 when William was just 15.
• In a 2007 interview with NBC, William, Duke of Cambridge, admitted that he has been called by the nickname she gave him since he was two.
• This follows royal news that the Duke andDuchess of Cambridge shared a rare insight into their personal relationships with their parents.

What did Princess Diana call Prince William as a child?

Diana, Princess of Wales, used to call William “wombat” when he was a child.

"I can’t get rid of it now. It began when I was two,” William said.

“I’ve been rightfully told because I can’t remember back that far, but when we went to Australia with our parents, and the wombat, you know, that’s the local animal.

"So I just basically got called that, not because I look like a wombat, or maybe I do.”

And this isn't the Duke's only nickname. The Duchess of Cambridge recently said that their children Prince George, six, and Princess Charlotte, five, call their father “pops”.

This comes after Prince William and Duchess Catherine shared a lovely post in honour of Sunday’s Father’s Day - which was also Will's 38th birthday.

The couple shared special photos via the Kensington Palace Instagram page to wish their fathers, and other fathers across the world, on the special day.

First the pair posted an absolutely adorable photo of Prince William cuddling up to his father Prince Charles while enjoying the outdoors.

The father and son were beaming at the camera while keeping warm in smart outdoor gear.

And the second photo shows a throwback photo of Duchess Catherine when she was a young child, sitting with her father Michael Middleton.
