Prince Louis Celebrates 5th Birthday with Fearless Fun and Cheeky Photos.

Prince William and Kate Middleton shared new photos of their youngest son, Prince Louis, ahead of his 5th birthday on Sunday. The photos, taken by British portrait photographer Millie Pilkington, show Louis smiling as he sits in a wheelbarrow pushed by his mother. The young royal was wearing a bright blue alpine-inspired sweater over a blue and white checkered collared shirt with blue shorts. The latest royal photo set marked a break with tradition as Kate usually takes the portraits of her family that are released for special occasions.
