The latest addition to the U.K. royal family is named Charlotte Elizabeth Diana, the prince and his wife Catherine, Duchess of Cambridge announced on Monday (04May15).
In a statement, the couple's representatives at Kensington Palace wrote, "The Duke and Duchess of Cambridge are delighted to announce that they have named their daughter Charlotte Elizabeth Diana. The baby will be known as Her Royal Highness Princess Charlotte of Cambridge."
The announcement came as the birth of Princess Charlotte on Saturday (02May15) was marked with a ceremonial gun salute across London on Monday (04May15).
Crowds gathered in the capital to watch as members of the military welcomed the new royal baby with simultaneous ceremonies at the Tower of London and in Hyde Park.
Shortly before the gun salute in Hyde Park, the Royal Artillery Band entertained the crowds by playing Isn't She Lovely, the song written by Stevie Wonder to celebrate the birth of his daughter Aisha.
Princess Charlotte is a sibling for William and Catherine's son Prince George, who turns two in July (15).
