Prince George Is Teen, Looks Like Prince William in 13th Birthday Photo

Prince George has officially been dubbed a teenager.

And the future king’s new portrait—released by the royal family on his 13th birthday July 22—proves he is looking more like his dad Prince William with each passing day.

In the picture, George softly smiles on steps in front of a window, donning a simple black suit and a white button up dress shirt with no tie and his hands in his pockets. Meanwhile, his strawberry blond hair is styled in a way totally reminiscient of his father’s signature look in the 1990s.

Of course, George’s new title of teenager isn’t the only way he has reminded the world that he isn’t just a little kid anymore. Last month, he made an appearance at the Royal Air Force Coningsby alongside Kate Middleton and the youngster stood at nearly the same height as his 5-foot-9-inch mom.

Plus, in September, George—older brother to Princess Charlotte, 11, and Prince Louis, 8—is expected to start Eton College, the same boarding school that his dad and uncle Prince Harry attended.

And ahead of that, George may reach another seminal milestone in a teenager’s life: getting his first cell phone.
