The British royals are in a party mood today! Prince William (40) and Princess Kate (41) have been married to each other since 2011. Two years later, the birth of their first child, Prince George (9), crowned their marital bliss. He was followed by Princess Charlotte (7) and Prince Louis. Like most parents, the royal couple is now realizing how quickly time flies: her youngest offspring Louis celebrates its fifth birthday today!

On Instagram the princely couple shared two sweet snapshots of him on the occasion of his son’s day of honor. Different than usual the pictures not by this time Kate snapped personally. Instead, she can be seen together in one of the photos with little Louis. The five-year-old sits beaming in a wheelbarrow full of greenery and lets his mum push him through the garden.

Numerous fans are enthusiastic about the cute shots and congratulate the Mini-Royal in the comments on his birthday. “Happy Birthday Louis! He’s the Prince’s Mini-Me”, an admirer commented on the post. “Such a nice photo with his mom,” says another user.
