The Duke and Duchess of Cambridge shared the heartfelt Mother's Day cards made by their children, in memory of Prince William's late mother, Diana, Princess of Wales.
And HELLO! couldn't help but notice the sweet way Princess Charlotte refers to her father.
Kensington Palace posted drawings made by Prince George, seven, Princess Charlotte, five, and two-year-old Prince Louis alongside their touching handwritten messages.

The message in Charlotte's card read: "Dear Granny Diana, I am thinking of you on Mother's Day, I love you very much. Papa is missing you. Lots of love Charlotte xxx."
While the young royal calls dad William "Papa," the Duke was overheard calling his daughter a French-inspired nickname in 2019, when George, Charlotte and Louis visited mum Kate's Back to Nature garden at the Chelsea Flower Show.
