LONDON (AP) — Britain's royal family has released the first official photos of month-old Princess Charlotte, photographed by her mother in the arms of elder brother Prince George. Kensington Palace issued four images Saturday, taken by the Duchess of Cambridge in mid-May at Anmer Hall, the family's home in eastern England. They show Charlotte propped on a pillow, cradled by George, who turns 2 in July. Charlotte wears a white sweater, the prince a white top trimmed in blue. Britain's royals have been photographed by some of the world's leading photographers. But Prince William and Kate are continuing a more informal tradition begun two years ago with the first official portrait of Prince George, taken by his grandfather Michael Middleton. Charlotte was born May 2 and is fourth in line to the throne.
