From Prince George's adorable wave during the Royal Tour of Canada in 2016 to photographing him and his sister Princess Charlotte at Pippa Middleton's wedding to James Matthews, and he finally got a smile from the car window.

And he's also pictured Princess Charlotte as the Duke and Duchess of Cambridge took her and brother George on a visit to Poland.

But he's not been able to take their portraits as mum Kate tends to always be behind the camera for those shots.

Kate previously took a snap of Prince George on his ninth birthday.

"Kate's a really excellent photographer. She's taken some great pictures of her children, and she shares them with us, which is nice," Arthur added.
