Pippa, 37, and her professional racing car driver James, 45, wed back in 2017 in a stunning ceremony in the U.K. before honeymooning in Australia. They welcomed their first child, a boy named Arthur Michael William Matthews, in October of 2018.
A source told Us Weekly at the time that "starting a family is something they've spoken about since long before they got married."
If the news is true then they will be a cousin to Prince George, 7, Prince Charlotte, 5, and Prince Louis, 2. And she will be pregnant alongside the Queen's granddaughter, Zara Tindall—who is expecting her third child with husband Mike Tindall.
No further details have been shared and the couple are yet to confirm the news publicly so stay tuned.
