Kate Middleton and Prince William's only daughter turns four on Thursday, and in celebration of her special day, Kensington Palace released a series of photos of the birthday girl one day early.
According to the palace, the adorable shots were photographed by the Duchess of Cambridge, who has a passion for art and photography.
Charlotte couldn't look any cuter in the snaps, sweetly posing and smiling for her mama at Kensington Palace and at their home in Norfolk.
Clearly, she's all grown up...
...but still so sweet!
The new pics come just over a week after Princess Charlotte's younger brother, Prince Louis, celebrated his first birthday on April 23, just two days after Queen Elizabeth II turned 93. Needless to say, Louis' photos (also snapped by Kate) were just as adorable:
Spring is certainly an exciting time for the royal family. In addition to Charlotte and Louis' birthdays, April 29 marked Kate and William's eight-year wedding anniversary, while May 18 will be one year since Meghan Markle and Prince Harry said "I do." On top of that, the Duke and Duchess of Sussex are also expecting their first child together "any day" now, a source told ET late last month.
Fans of the royals have been patiently waiting for the announcement that Baby Sussex is here, and some have been passing the time by coming up with their own theories. Read them here, and watch the video below for more on the royal family!
