Just nine days after the arrival of her new brother, Princess Charlotte — now the middle child of Prince William and Kate Middleton — celebrated her third birthday Wednesday.
Kensington Palace marked the occasion by posting a headshot of the little princess on social media.
The photo was taken in January when she started nursery school and was being re-shared with followers.
Princess Charlotte is fourth in line to the throne and is rumored to be the flower girl to her uncle, Prince Harry, when he marries Meghan Markle on May 19.
Princess Charlotte was the flower girl for her aunt, Pippa Middleton, when she wed race car driver James Matthews last May.
The young princess has been charming crowds since she was a baby.
Last week, she delighted onlookers outside St. Mary’s Hospital in London by waving as she visited her baby brother, Prince Louis.
When her great-grandmother, Queen Elizabeth II, turned 90 in 2016, Charlotte was in awe of the Royal Air Force flying over Buckingham Palace.
When her parents marked her first birthday in 2016, they posted images of her pushing around toys in a pink dress and another shot of her wearing a knit sweater, which had social media gushing.
"So much sweetness. Thank you so much for sharing," one follower commented.
Another wrote: "She is SO cute!! Looks so much like her brother!!"
The toddler has also become a fashion icon in her short time on earth.
After the princess turned 2, Kensington Palace released an image of her in a $23 yellow sweater from British retailer John Lewis, which promptly sold out.
Princess Charlotte shares her birthday with another British icon — David Beckham, who turned 43 Wednesday.
After Charlotte’s parents welcomed Prince Louis, the former England skipper congratulated the couple and the whole royal family on Instagram.
