Prince George
In just a year, Prince George of Cambridge made some cute faces in public. Reuters

As third in line to the throne, Prince George Alexander Louis of Cambridge may one day be the royal face of the United Kingdom. He has already shown his future subjects many cute faces of his own.

Prince George, who celebrates his first birthday on July 22, has already led a busy life. He made his public debut at one-day old, when his parents, William and Kate, presented him to the press and the eager crowds outside the hospital where he was born. He’s already racked up three weeks’ worth of air miles on a tour of New Zealand and Australia. He’s battled a bilby and even had to interact with his subjects in a mandatory playdate Down Under.

In honor of his first birthday, here are some of the many faces of Prince George.
