It looks like 3 is the magic number in the Middleton family. While Kate Middleton is mother to Prince George, 8, Princess Charlotte, 7, and Prince Louis, 4, it was just reported that her younger sister, Pippa, is now expecting her third child as well.
The news was first speculated last night when Pippa attended the Platinum Party at the Palace and seemed to have her arms wrapped around a baby bump while she sported a lime green, long-sleeve dress from ME+EM London.
Now, PEOPLE reported that multiple sources have confirmed the news of Pippa's pregnancy, but a representative declined the publication's request for comment.
