Now, a new adorable picture of the Duke of Cambridge and his youngest child has been released to mark Father’s Day.
Louis can be seen being guided by his father - pulling a funny face at him - on a rope swing in the ‘Back to Nature’ garden his mum Kate Middleton designed.
It was simply captioned: “Happy Father’s Day!”
The post also paid tribute in another image to Prince Charles.
William and his father can be seen in the shot, taken in 2012, at RAF Valley in Anglesey.
The Duke was then serving a three-year tour with the RAF Search and Rescue Force.
Royal fans were delighted with the adorable father-son pics, and the post has already received 120k ‘likes’.
