Two new portraits have today been released by Kensington Palace, marking both Father's Day and the Duke of Cambridge's 38th birthday.
The adorable photographs were shared to the Kensington Palace social media pages and are the latest to be taken by the Duchess of Cambridge.
In the images, William is seen playing on the grass with his children, 2-year-old Prince Louis, Princess Charlotte, 5, and Prince George, 6.
The Duke and his children can also be seen sitting and standing on a swing that was a gift from the Duke's father, Prince Charles, as a wedding present to William and Kate.
