Pippa Middleton and husband James Matthews have welcomed their second child, a baby girl, and — just like they did with their two-year-old son — the couple opted for a three-part moniker: Grace Elizabeth Jane.

According to People, the younger sister of Kate Middleton gave birth to Grace early Monday morning.

Pippa's newborn daughter now has a very sweet connection to her Aunt Kate – they both have the middle name Elizabeth. (The Duchess of Cambridge was born Catherine Elizabeth Middleton.) Of course, Grace also shares the name with Queen Elizabeth, who so happens to be Kate's grandmother-in-law!

Pippa's mother, Carole Middleton, first confirmed the news that Pippa was pregnant during an interview with Good Housekeeping UK, when she casually made reference to her new grandchild. "I hope to see more of my family than I could last year, including, of course, my new grandchild," she told the publication.

Pippa and James first became parents in October 2018, when they welcomed Arthur Michael William at London's St. Mary's Hospital – the same facility where Kate Middleton gave birth to Prince George, Princess Charlotte, and Prince Louis.
