Kate Middleton and Prince Williams social media accounts posted a sweet tribute with a special, previously unseen photo to mark Fathers Day on Sunday.

The royals account shared a video message with four pictures alongside the caption, Wishing fathers everywhere a happy Fathers Day.

The never-before-seen snap shows William with his three children: Prince George, Princess Charlotte and Prince Louis.

The royal holds little Louis, while George hugs his fathers leg and Charlotte gives the camera a sweet smile. The photo is from 2019s Trooping the Colour celebration.
