Princess Charlotte sadly may never have met her "granny Diana" but royal enthusiasts believe the spirit of the late Princess Diana is burning bright in her look-alike granddaughter.
Just like when Diana was a little girl, the pair share the same soft smile, sparkling eyes and cheeky expression.
What's more, after Prince William and Duchess Catherine's only daughter, whose full name is Charlotte Elizabeth Diana of Cambridge, was filmed showing off her charismatic personality telling off photographers outside the chapel and reminding them: "you're not coming", well-wishers believe Charlotte has the same lively spirit as Diana.
"Princess Charlotte displays, already, charisma, charm, fun, & joy. She embodies the soul & spirit of Diana. She just makes one smile when you see her image," one person wrote on Twitter.
"Charlotte looks like and reminds me of Princess Diana," another agreed.
"I have been saying - for a while now - that Charlotte is going to look a lot more like Diana than anyone thinks," a third claimed.
A fourth pointed out: "The lips and the way she is smiling is similar to Diana."
Slide across to see Princess Diana as a little girl vs. Princess Charlotte!
While others think the fourth in line to the British throne is her "Gan Gan" The Queen's doppleganger.
One person admitted: "Is it just me or does this girl look a lot like the Queen?"
Within minutes, people rushed to agree, with another quipping, "1st thing that crossed my mind when I saw this picture!"
"The Queen just amazing look at pictures of the Queen when she was young dead spit of her," another used said.

No matter who she takes after, it's clear Princess Charlotte is growing into one sweet little girl.
According to a her proud parents, the tiny royal is as charming and sweet as she looks!
William says his daughter is "obsessed" with fashion, "mad about pink" and "loves dancing."
While The Queen has confessed her great-granddaughter is very much in charge - and she especially loves to boss her four-year-old big brother Prince George around.
Last year in a documentary called Diana, Our Mother: Her Life and Legacy to celebrate Princess Diana, 20 years after her untimely death, Prince William opened up about keeping "Granny Diana's" memory alive for his three young children.
"So we've got more photos up round the house now of her and we talk about her a bit and stuff. And it's hard because obviously Catherine didn't know her, so she cannot really provide that - that level of detail," he said.
"So I do regularly put George or Charlotte to bed, talk about her and just try and remind them that there are two grandmothers, there were two grandmothers in their lives, and so it's important that they - they know who she was and that she existed."
As for what kind of a grandmother she would have been like, William quipped: "She'd be a nightmare grandmother, absolute nightmare. She'd love the children to bits, but she'd be an absolute nightmare."
"She'd come and go and she'd come in probably at bath time, cause an amazing amount of scene, bubbles everywhere, bathwater all over the place and - and then leave."
