Instagram fan account Prince George Charlotte Louis shared the amazing picture, simply captioning: "Woah."
The picture has been liked over 20,000 and garnered nearly as many comments.
"I knew she was a Windsor but this is crazy!!" one fan wrote.
Another added, "She really is her father."
A third echoed, "That face!"
However, a lot of other fans think the little princess is looking more and more like her mother, Kate Middleton
The adorable three-year-old stepped out to attend her little brother, Prince Louis', royal christening, earlier this year and the Internet couldn't get over the young royals resemblance to her famous mum.
Rocking a sweet blue floral dress with matching shoes and headband, Charlotte once again stole the show.
However, despite many noticing the similarities between Charlotte and her mother and grandmother, the most noteworthy similarities that royal fans have picked up on is that of the three-year-old royal and her great-grandmother.
