Is Prince George the spitting image of Dad in his new official portrait?
The photo – which was released to mark George's first birthday on Tuesday – resembles one of his father, Prince William, at 18 months old.
Comparing the father-son portraits side-by-side, the family connection is clear: They share the same side-parted blonde hair and happy little faces. Plus, both princes look dashing in blue.
Of course, we already knew George is every bit a Windsor from his uncanny resemblance to great-granny Queen Elizabeth II.
