Prince William and Kate’s newborn niece joins big brother Arthur Michael William Matthews and big sister Grace Elizabeth Jane. Pippa became a mom in 2018 with the birth of her son Arthur. Her and James’ second child, Grace, was born in March 2021.

Pippa’s baby bump was on display last month at the Platinum Party at the Palace concert. A source told Page Six at the time that Pippa and James are “so happy,” and that the Duchess’ sister is a “natural mama.”

It’s been an exciting few weeks for Princess Charlotte’s aunt. In addition to the arrival of her third child, Pippa recently graduated with her master’s degree from the University of Wales Trinity Saint David. In a press release shared by the university last week, the UWTSD Physical Education, Sport and Physical Literacy graduate admitted that “committing to a full-time master’s degree” while working from home with her young kids had “been challenging,” but “credited the University for its support.”

“Getting back into studying took some getting used to but I felt really well supported by the team at UWTSD. The nature of the course being divided into specific modules also meant that it was easier to compartmentalise what was required each term,” Pippa said.

“The modules were all really varied and interesting allowing enough flexibility to channel the course to your passions – for me it was early years’ physical development,” she added. “I have enjoyed the balance of work and motherhood and getting back into reading, writing, and learning again.”
