Royal Family marks Prince Louis 3rd birthday with a snap as he pose on his bike as he heads out on his first day of nursery school

Prince Louis is celebrating his third birthday today, April 23 and  Louis' mother, the Duchess of Cambridge took the picture in the grounds of Kensington Palace on Wednesday, April 21, before he left for his first day of nursery school.

 The snap was uploaded on the verified handle of the Royal family. 

Just so you know, Prince happens to be the third child of Prince William and Kate Middleton. 

He was seen rocking a jumper, shirt and shorts, with a rucksack on his back while smiling on his bike. 

It looks like he was cycling to nearby Willcocks Nursery School in west London.
