On his first day of nursery, Prince Louis posed for a photo in a stylish outfit to mark this third birthday.
The picture, which was taken by his proud mum the Duchess of Cambridge, was shared on Kensington Palace's social media yesterday.
Louis was super adorable in a navy blue jumper, chino shorts and a pair of trendy trainers from adidas - one of Kate Middleton's go-to brands.

Smiling at the camera, Louis looked excited for his first day at the Willcocks Nursery School in Kensington.
The adorable snap was shared to social media on Thursday evening, along with the caption: "Three tomorrow! Taken earlier this week by The Duchess before he left for his first day of nursery, The Duke and Duchess are pleased to share a new image of Prince Louis."
Mum Kate has also been pictures in several pairs of adidas trainers during public engagements.
