George, the oldest child of Kate and Prince William's three children, was in the spotlight recently when he joined his parents at London's Wembley Stadium to watch England compete in the UEFA European Championship.

He watched England win in an earlier round but then saw the team lose to Italy in the finals earlier this month.

George will celebrate his birthday privately with his family, which also includes his younger sister, 6-year-old Princess Charlotte, and 3-year-old Prince Louis.

It has become a family tradition for Prince William and Duchess Kate to share new photos to mark the birthdays of each of their children.

Here is a look back at the photos of Prince George released each year for his birthday.
