Prince George has taken part in a number of official engagements during the Queen's Platinum Jubilee celebrations.
This has led many royal fans to comment on how the eight-year-old is fast becoming the spitting image of his father Prince William, 39.
The pair were spotted side-by-side sporting very similar facial expressions at Saturday night's Platinum Party at the Palace concert, and also greeted crowds together at Cardiff Castle earlier in the day.
It follows their appearance – along with the rest of the Cambridge family, the monarch and other senior royals – on the Buckingham Palace balcony following Trooping the Colour on Thursday.
As such, fans have noticed the strong likeness between the Duke of Cambridge and his eldest son.
In a post on Twitter one person wrote: "Love how George is Prince William's little mini-me."
Another commented: "Doesn’t royal highness Prince George look like his dad his royal highness Prince William?"
A third shared: "George is Wills' spitting image."
The physical resemblance between the duke and prince was also discussed last year during the UEFA Euro 2020 final when they watched the game together at Wembley Stadium.
Many believe that George looks strikingly similar to how his father looked at the same age, with almost identical blonde hairstyles.
Comparisons between the two have been present over the years also because the youngster has been dressed in a number of hand-me-down outfits from his father.
