Royal fans were delighted to discover Princess Charlotte has a doppelganger - the niece of the late Queen Elizabeth.
A picture of 7-year-old Charlotte, taken as the family attended church in Sandringham on Christmas day, was placed next to photo of Lady Sarah Chatto, 58, as a child and the resemblance is uncanny.
Sarah is the only niece of Queen Elizabeth and was the second child and only daughter of Princess Margaret and her husband Antony Armstrong-Jones.
She is the first cousin of King Charles and lives a private life as a painter, while her doppelgänger is due to be the next Princess Royal.
Twitter page @RoyalFamilyGB posted an unearthed picture of Sarah from 1970 alongside the photo of Charlotte from 2022, The Express reports.
The pair have recognisable features with the same button noses, similar eye and mouth shape, and each wearing a similar half-up hair do.
Royal fans exclaimed on social media:"oh wow! Such a close resemblance! I would have thought that was Charlotte! They are identical."
Twitter user @SusanRutherfo13 called the two royals "twins. Fifty years apart."
Meanwhile @EvelynMJean said: "Now that really is extraordinary. Two absolutely beautiful children. So sweet."
Another added: "That’s who she reminds me of. Of the three children she’s most like the Windsor side of the family."
Royal fans have also noted that Lady Sarah Chatto is not the only relative that Princess Charlotte shares a likeness with.
Others have noted that Charlotte also resembles a young Queen Elizabeth II and Princess Diana, as well as Lady Kitty Spencer, the niece of the former Princess of Wales.
One Twitter user previously stated: "I get so confused with Charlotte…I see Lady Sarah a lot, but I also see a faint glimpse of Catherine…also the Queen and William and Diana are there as well. Genetics are so interesting!"
Not only are royal fans finding the similarities confusing, so does the future king and Charlotte’s father himself.
In a visit to Bradford in 2020, William saw a photograph of himself dressed in a red jumpsuit from 1992 and was shocked at the resemblance to his daughter.
The future King was seen doing a double take and turning to the Duchess of Cambridge saying: "Is that me? Doesn’t it look like Charlotte?"
Kate stepped closer to examine the photograph and agreed with her husband, saying: "It looks so much like Charlotte."
William was so stunned he said again: "Is that me? That looks just like Charlotte.
"That’s incredible, I haven’t seen that before. Very alike in similarity."
