Kate Middleton shares Prince George and Princess Charlotte’s adorable nickname for Prince William

How sweet.

Kate Middleton has revealed the sweet nickname Prince George and Princess Charlotte have for their dad, Prince William. The Duke and Duchess of Cambridge visited Leicester on Wednesday, paying tribute to Vichai Srivaddhanaprabha,the late chairman of the city's football club. During the visit, Kate spoke to some of the volunteers who were helping relocate the flowers - as well as the other tributes - to a dedicated site. The 36-year-old said that her three children - Prince George, 5; three-year-old Princess Charlotte; and Prince Louis, 7 months -were doing "great", as she revealed the royal siblings' adorable nickname for their dad. According to PEOPLE season ticket holder Fiona Sturgess told the press:

"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?’ “,

And it seems like most of the royal family goes by some form of nickname - at least, among each other. Prince George and Princess Charlotte reportedly call Prince Charles "Grandpa Wales" and Prince Phillip is said to refer to Queen Elizabeth as "cabbage". Meanwhile, Prince Phillip is said to call his new daughter-in-law, Meghan Markle, Tungsten - yes, really. Meghan reportedly calls Queen Elizabeth "Queen Mama, and refers to Prince Harry as "my love". And Prince William is said to refer to Kate Middleton as "poppet", while she calls him "my love".
