Prince George and Princess Charlotte's new surname has been confirmed today.
There had been much speculation over whether the Cambridge children would need a change of name following the death of their grandmother, Queen Elizabeth. Since the 96-year-old monarch's death, the young royal's dad, William, and his wife Kate, have had a change of title.
Previously known as the Duke and Duchess of Cambridge Kate and William are now known as the Prince and Princess of Wales. Royals don't tend to have an official surname, but their children were known as George and Charlotte Cambridge for education and work purposes.
