Be it flowy summer dresses or monotone winter outfits, the Duchess of Cambridge knows how to make heads turn every time she steps out.
The card was made by Alma Shahar, six, whose father Yair Shahar, 49, had been given critical treatment by the air ambulance after being run over by a auto when cycling in Edmonton, north London, in 2016.
The group gave William a card for his wife's birthday, which was made by a group of children, according to the U.K.'s Hello magazine.
Alma wrote in the card: "Kate, I hope you've had the best birthday you could ever imagine".
The palace wished Middleton a happy birthday on the palace and the royal family's official Twitter accounts.
She thanked the public for their "lovely messages" as she celebrated.
Kate has also become an aunt to sister Pippa Matthews's baby son Arthur, and the Cambridges are also awaiting the arrival of the Duke and Duchess of Sussex's first child in the spring - another cousin for George, Charlotte and Louis.
He arrived in style: William, who worked as an air ambulance pilot for around two years in East Anglia, touched down in one of the London Air Ambulance charity's helicopters.
"I can't go back without a gift of a helicopter, George will never forgive me", William added of his eldest child.
She spent her early years in Berkshire and Amman, Jordan, and from the age of 13 attended Marlborough College, an exclusive private school in Wiltshire.
The duchess-to-be met and began dating William while studying art history at St Andrew's University, where she studied history of art.
