Interestingly, when viewing these christening pictures I noticed two photos of George that I think reveal this. Look at the photo below of Michael Middleton and Prince George, then look at the last photo of George. I believe it is easy to see he favors his mother, the Duchess of Cambridge's father, Mr. Middleton. Prince George is a miniature of Michael Middleton, just call him Jr.!
It just goes to show, no one has a monopoly on looks, not even the royal family! What do you think?
In this last photo Princess Charlotte does appear to look like her mother, which is not surprising although time will tell.
Below I have included artwork dedicated to her christening, perfect for a little girl's room or nursery. If you would like to see it in full size just click the link below.
