Princess Charlotte has turned 10 years old around two weeks after her younger brother Prince Louis. The third in line to the throne may well get a chance to celebrate with her friends at Lambrook School, in Berkshire, as she marks the milestone birthday.

Kate, who announced her remission from cancer in January, has slowly resumed her royal duties. She recently made a public appearance on St. Patrick’s Day in London, attending the Irish Guards’ annual parade in a dark-green Alexander McQueen coat and hat.
