Prince George performed a very important duty at his aunt Pippa Middleton's wedding on the weekend, serving as a pageboy at the ceremony.
The young Prince walked down the aisle of St. Marks Church in Englefield alongside several other pageboys, who all wore the same white shirt and green pants with knee-high socks.
Adorable, of course.
Prince William had several starring role's in royal weddings when he was younger, too, and the photos prove that George is every bit his father's mini-me.
Back in 1988, William wore a similar style of outfit in a pink colour-scheme at the wedding of Camilla Dunnes. Take a look at the two photos below and tell us they're not identical:
Will might be a little older in that photo, but the resemblance is uncanny.
The Prince also fulfilled pageboy duties at the royal wedding of his uncle Prince Andrew and Sarah Ferguson, in a sailor-inspired outfit, no less. Will looks exactly like his young son in photos from the day, which were taken 31 years earlier.
