Prince George turns 6 years old today — and in that short time he's managed to capture the hearts of millions across the globe.

The first child of Prince William and Kate Middleton is third in line to the British throne and he has already had his fair share of spotlight. From high-profile meetings with world leaders to quality time with his family, George manages to attract attention wherever he goes.

Here are several times where the future king made our collective hearts melt.

READY FOR HIS CLOSE-UP

Say cheese!

This endearing picture was taken one year ago, shortly before George's fifth birthday, when the royal family came together for the christening of his then-newborn brother, Louis.

In response to the image, some followers of the family noted George's stronger-than-usual resemblance to his grandmother, Queen Elizabeth II.

FAMILY AFFAIR

This family photo was taken in early 2017, showcasing the Duke and Duchess of Cambridge with their two children.

In this picture, George's blonde hair is especially radiant, as he is seen clutching the hand of his father, Prince William, while wearing a striped blue dress shirt to match the rest of the family's color scheme.

Too cute!

One of George's first royal pictures came early in his life when he was photographed as an infant while being held by his father, Prince William, as the family departed Wellington, New Zealand.
