Prince William, Kate Middleton mark fourth birthday of Prince Louis with new photos

Duke of Cambridge Prince William and his wife Kate Middleton delighted the royal fans with sweet photographs of their youngest child Louis to mark his fourth birthday.

Kate posted the photos with caption, “4 years old tomorrow!”

The photographs of Louis, who turns four on Saturday, were taken by Kate in Norfolk, east England, and show him smiling, holding a cricket ball and running along a beach.

Louis is a great-grandson of Queen Elizabeth II, and fifth in line to the throne, behind his grandfather Charles, father William and siblings George and Charlotte.
