Prince Charles' office says his wife has become a grandmother for the third _ and fourth _ time.
Clarence House says Laura Lopes, the daughter of Camilla, Duchess of Cornwall, gave birth to twin boys on Wednesday. The boys have been named Louis and Gus.
Camilla already has two other grandchildren. Lopes has a 23-month-old daughter with husband Harry, and her son Tom Parker Bowles has a 2-year-old daughter with his wife Sara.
A Clarence House spokesman said Thursday that mother and sons are doing well and that Camilla is "absolutely delighted."
