Pippa Middleton and James Matthews are officially a family of five.
The younger sister of Kate Middleton welcomed her third child — a baby girl — a couple of weeks ago, PEOPLE has learned.
Pippa, 38, and James, 46, welcomed their first child — a son named Arthur — in Oct. 2018. She gave birth to a baby girl named Grace in March 2021. She followed in the footsteps of her royal sister by giving birth in the Lindo Wing of St. Mary’s Hospital — the same place where Kate and Prince William welcomed all three of their children.
Pippa’s baby bump was on display in a bright green dress at the star-studded “Party at the Palace” concert for Queen Elizabeth’s Platinum Jubilee last month. She was joined by Matthews, her brother James Middleton and his wife Alizée Thévenet.

The baby girl is the sixth grandchild for Carole and Michael Middleton and another little cousin for Prince George, Princess Charlotte and Prince Louis.
Pippa’s three children can look forward to lots of playdates with their royal cousins in the future. According to a source, Pippa and her family are planning a move to a village near Bucklebury, in Berkshire, where Pippa and her siblings grew up and where their parents still live. Their new home will be about 50 minutes from Windsor — where Kate, William and their three children are relocating this summer.
