Princess Charlotte today celebrates her fifth birthday - and her parents Prince William and Kate Middleton have released a selection of new pictures of her volunteering to mark the occasion.

They show the youngster delivering fresh, homemade pasta to vulnerable and isolated pensioners near the family’s Norfolk country home of Anmer Hall on the Sandringham Estate.

However, many royal fans couldn’t help but notice just how much she looked just like particular close relatives.

They suggested that - rather than the Duchess of Cambridge or her siblings - she had a closer physical resemblance to the Duke of Cambridge, as well as the Queen, Princess Diana and Lady Sarah Chatto.

While most of the images were candid shots taken last month, it was a new portrait of Charlotte that seems to have sparked one of the more popular comparisons.

Its regal nature drew many Twitter users to claim she was the spitting image of Her Majesty as a young girl.

Indeed, old photos of her great-grandmother, now 94, do show a striking resemblance between the pair.

One person wrote that all could see is “the Queen’s timeless face and expression” in the picture.

Some also claimed she resembles Lady Sarah Chatto as a child (pictured, left, in 1969 aged five) (Getty Images)

Similarly, comparisons have been made between Charlotte and second cousin Lady Sarah Chatto - the Queen’s niece - as a child.

Royal commentator Victoria Arbiter pointed out that the pair, as well as looking very similar, also almost share a birthday.

Sarah - who is the daughter of the monarch’s late sister Princess Margaret and Antony Armstrong-Jones, the 1st Earl of Snowdon - turned 56 yesterday.

Several other social media users agreed that the likeness was “uncanny”.

Perhaps two of the most popular similarities floated were between Charlotte and her father William, now 37, and also her grandmother, the late Princess Diana.

One Instagram user pointed out that all three had the same “little mischievous smile”.

Another, on Twitter, described her as the duke’s “mini me”.

They noted that while Prince George, six, and Prince Louis, two, look just like their mum, Charlotte is the “only one of Cambridge kids who resembles him”.

It comes as William and Kate released a brand new picture of Charlotte to mark her fifth birthday today.

In a post on the Duke and Duchess of Cambridge’s Instagram account, their only daughter - and middle child - can be seen holding a bag of fresh, homemade pasta.

Captioning the snap, likely to have been taken at the family’s Norfolk home Anmer hall where they are in lockdown, they wrote: “Thank you for all your lovely messages on Princess Charlotte’s fifth birthday!

“The Duke and Duchess of Cambridge are very pleased to share a new photograph of Princess Charlotte, taken by The Duchess this April.”
