Kate Middleton's sister gave birth to her third child

Pippa and James Matthews have a new addition to the family. Now a 3-year-old son Arthur and one-year-old Grace are joined by another girl, whose name is not yet reported. It is known that the sister of the Duchess of Cambridge became a mother for the third time two weeks ago in the same St. Mary's Hospital in London, where Kate gave birth to all three children.

Pippa's third pregnancy first became known in June, when she and her husband appeared at a concert celebrating the 70th anniversary of the reign of Elizabeth II, wearing a bright green dress that emphasized her rounded belly.

Now the Matthewses are about to move with their children to a larger house with a garden in Bucklebury, Berkshire, where Pippa and Kate's parents live. The Dukes of Cambridge, who are going to spend this summer in Windsor, will also be an hour away.
