Princess Charlotte, the second-eldest child of Prince William and Kate, the Princess of Wales, is celebrating her 10th birthday.
William and Kate marked their daughter's birthday by sharing a new photo of Charlotte on social media.
The photo, taken by Kate, shows a smiling Charlotte wearing a backpack and a camouflage jacket while sitting outside with mountains in the background.
"Happy 10th Birthday Princess Charlotte! ❤," the photo's caption reads.
Charlotte was born May 2, 2015, at St. Mary's Hospital in London, the same hospital where her brothers, Princes George and Louis, were also born.
The only daughter of William and Kate, Charlotte's full name, Charlotte Elizabeth Diana, is a tribute to her great-grandmother, the late Queen Elizabeth II, and her grandmother, the late Princess Diana.
As William and Kate's second child, Charlotte is third in line to the throne, behind her father and older brother George.
