As Prince George marks his 12th birthday today (July 22), fans across the world are sharing warm wishes—and some have sparked a lively debate over who the young royal resembles most.

Despite his young age, Prince George has already become one of the most admired members of the royal family. He’s even started taking part in official engagements alongside his parents, Prince William and Kate Middleton.

As he grows older, royal watchers have taken note of how much he looks like certain members of his extended family, particularly on his father’s side.

Spencer Family Resemblance?

Some royal fans believe George bears a strong resemblance to his late grandmother, Princess Diana, née Diana Frances Spencer.

But it’s not just Diana they see in him. One fan on TikTok compiled a comparison video of George with various Spencer family members, including his great-grandfather John Spencer, great-uncle Charles Spencer, and Charles’ son, Louis Spencer. The video caption read: “You can even see his Granny Diana in him,” along with a heart emoji.
