The child will be the younger sister to Pippa's two-year-old boy, Arthur Matthews.
Pippa and her husband James Matthews named their new daughter Grace Elizabeth James. She was born on March 15th, 4:22 am, weighing 6lbs and 7oz, at St. Mary's Hospital, where Kate and William also welcomed all of their little ones.
Pippa Middleton Gives Birth
According to a source from PEOPLE, mother and baby are doing swimmingly, and the royal family is thrilled at the newest arrival.
The child's namesake has familial origins. Her middle name is shared with her aunt Kate, who was born Catherine Elizabeth Middleton. We're sure you can guess who else shares the name Elizabeth in the extended family. Wink-wink.
Pippa and her husband wed back in 2017 at St. Mark's Church Englefield, in Berkshire. She wore a lacy, cream-colored Alexander McQueen gown for the special day. Her sister took on an understated role at the wedding as not to upstage her sister, as the future queen would have drawn too much attention.
Fast forward to now, Pippa now has a second child, growing her and her husband's small and low-profile family.
Congratulations to the couple on their newest arrival!
