Pippa Middleton, the younger sister of the Duchess of Cambridge, is reportedly expecting her first child with husband James Matthews. Sources cited in British media say she has already revealed the big news to family and friends after getting a 12-week scan last week. Kate Middleton, who is about to give birth to her third child with Prince William, reportedly “could not have been more delighted” with the news. A friend quoted by the Sunday Express said Pippa’s pregnancy had provided “much-needed happiness” to the family. The news comes just weeks after David Matthews, Pippa’s father-in-law, was charged by French authorities for the alleged rape of a minor.
