These forgotten photos of Prince William as a young boy show how Prince Louis is the spitting image of his father.
Photos that appear to have been taken at the Sandringham estate in 1990 show the Duke of Cambridge wearing a dark red jacket and riding a bike.
In another image, Prince Charles is riding alongside William with six-year-old Prince Harry on the back.
Prince William was snapped looking at the camera as he wore a Parker jacket and riding boots.
In one image William resembles Prince Louis, as they both have rose-blushed cheeks, blonde hair and blue eyes.
It isn't the first time Louis, four, has been compared to William.
Last month during the Platinum Jubilee, Louis stole the show with his cheeky personality, dancing and pulling funny faces.
Louis was spotted wearing a sailor outfit that the Duke of Cambridge has previously worn, but as MyLondon reports, an unearthed photo from William's childhood has really highlighted the spitting image.
A snap from 1985 of three-year-old Prince William and his father, Prince Charles, on the royal yacht 'Britannia' has resurfaced online.
Young William appears to be wearing the same white and blue outfit that Louis wore while watching the Jubilee Pageant on Sunday, June 5.
William's hair is cut in a similar style to Louis' and he can be seen with his arms up over his head.
Taking to Twitter, one royal fan pointed out: "Louis looks like Prince William in this photo."
Another agreed, writing: "Prince Louis looks the most like Prince William oh my god.
Prince William and his wife Kate Middleton enjoy sharing images of their children on social media when celebrating milestones, which has prompted royal fans to notice the uncanny resemblance between the Duke and his children.
His parents shared a picture of Prince George last week to celebrate his birthday, and many said the third-in-line to the throne looked just like his father.
Last year, the birthday boy was photographed posing in a striped polo on top of a Land Rover Defender, in a touching tribute to his late great-grandfather, Prince Philip.
And for his seventh birthday in 2020, the young prince looked ready for action, donning a camouflage T-shirt during a family stay at the Queen’s Sandringham estate in Norfolk.
