The Queen was photographed as she left Kensington Palace after visiting her newborn great-granddaugther.
On May 2, the day of Charlotte's arrival, Queen Elizabeth wore an all-pink ensemble as she attended the amalgamation parade of the Queen's Royal Lancers and 9th/12th Royal Lancers. The color choice was seen as a way to celebrate the birth of her granddaughter.
It was a big day for Charlotte as the fourth-in-line to the British throne was also registered on Tuesday.
Will signed the document as "His Royal Highness Prince William Arthur Philip Louis Duke of Cambridge." Kate Middleton's full name, Catherine Elizabeth, was used for the document as was her enviable occupation: "Princess of the United Kingdom."
Charlotte weighed in at 8lbs, 3 oz., and Kate was out of the hospital in less than 12 hours after delivery.
There's still one family member who has yet to meet the latest addition to the royal family though! Her uncle Prince Harry is currently in a month-long secondment with the Australian Defence Force, but he said, "I can't wait to meet her," in a statement.
