What Prince Louis will look like when he is older

Many royal fans agree Prince Louis is the child of the Prince and Princess of Wales who looks most like the Middletons.

Royal fans regularly debate who the younger members of the Firm have taken after every time new photographs of the children are released. While they are still young, Prince George, Princess Charlotte and Prince Louis are already showing similarities with their parents and elderly relatives. Among the children of the Prince and Princess of Wales, their youngest son is the one many royal supporters think has taken after the Middleton family the most.

Now, using an app with an ageing filter, looked into how the three children of Prince William and Kate, Princess of Wales, may look like in a few decades.

Many royal fans agree the five-year-old is the royal child who resembles the most Kate’s side of the family.

In particular, royal supporters believe Louis looks like his grandfather Michael Middleton. And pictures showing an aged-up Louis appear to confirm the resemblance.

Mr Middleton and his wife Carole Middleton were among the guests at Westminster Abbey on Saturday.

However, given they aren’t members of the Firm, they sat rows behind Kate, her husband and her children, who were instead placed prominently in the front of the abbey.

No public interaction happened between the Middletons and the Wales family members during the service.

While Mr and Mrs Middleton left the abbey by car after the service ended, Kate, William and their children headed to Buckingham Palace aboard the Diamond Jubilee State Coach.

During the trip, which saw the carriage procession pass through Whitehall, Trafalgar Square and The Mall before reaching its destination, Prince Louis waved enthusiastically at the crowds lining the streets.

Princess Charlotte

The only daughter of Kate and William turned eight earlier this month.

She has often been called a mini-me of Queen Elizabeth II, but in recent years some royal fans have also started to say she shares similar traits to her mother.

Indeed, in the aged-up pictures, the young royal seems to share a keen likeness with Kate, in particular when it comes to her eyes’ shape and her lips.

Prince George

Since his birth, Prince George has been compared to a few members of his extended family when it comes to likeness, including his great-uncle Charles Spencer and uncle James Middleton.

As a young baby, the now-nine-year-old looked just like Prince William when he was also a child.

His aged-up pictures, however, don’t make it any easier to decipher who he has taken after the most, as he bears a resemblance with both his mother’s and father’s sides of the family.
