The adorable name Prince William's children call him

All of us have a special name for our parents – whether it's 'mum' or 'dad', 'ma' or 'pa', 'mother' or 'father' or even the 'old man'.

But now we know which name Prince William goes by.

Kate, the Duchess of Cambridge, has revealed the nickname Prince George and Princess Charlotte use when referring to their dad.

He's known as 'pops'. So cute.

Kate made the revelation during a visit to Leicester City where she and William paid tribute to the football club's owner, Vichai Srivaddhanaprabha, who was killed in a fiery helicopter crash.

The royal couple met with the club's staff and volunteers, including one who asked Kate how Prince George, Princess Charlotte and Prince Louis were doing.

Kate replied, "They are great, thank you".

Season ticket holder Fiona Sturgess had a few minutes with the Duchess, and later told reporters about their conversation.

"Kate said that William was playing football with the children last night and one of them said, I think it was George, 'Are you playing football tomorrow, Pops?'"

Earlier this month, Prince Charles revealed the Cambridge children call him 'Grandpa Wales' while Queen Elizabeth is known as 'Gan Gan' to her great-grandchildren.

During Kate and William's visit to the Leicester Football Club overnight, they were presented with mini team uniforms in personalised boxes bearing their children's names.

"They’ll be fighting over the Leicester and Aston Villa kits," Prince William joked.

"That’s very kind, that’s brilliant."

Prince William is head of the Football Association and an avid Aston Villa fan.
