Prince George just keeps getting cuter and cuter. Every time we see him, the wee Royal manages to melt our hearts — just look at him pouting in Poland earlier this week! The four-year-old just gave us our biggest dose of adorable yet, however, with his official birthday portrait.

Our favorite miniature prince celebrated his big day on July 22 by gifting the world with an unbelievably sweet snap in which he’s all smiles (excited about all the presents he’s going to get, perhaps?!), sporting a stylish blue and white striped button-down shirt with his picture-perfect blonde hair combed to one side.

“The Duke and Duchess are delighted to share a new official portrait of Prince George to mark His Royal Highness’s fourth birthday,” reads the photo’s official caption. “The photograph was taken at Kensington Palace at the end of June by Chris Jackson. The Duke and Duchess are very pleased to share this lovely picture as they celebrate Prince George’s fourth birthday, and would like to thank everyone for all of the kind messages they have received.”

The Royal photographer also took to Twitter to share a compilation of some of his personal favorite pics from the past four years, saying that he’s “honored that the Duke and Duchess of Cambridge have chosen to release this portrait I took to celebrate Prince George’s fourth Birthday.”

Happy birthday, Prince George!
