Kate Middleton will become an aunt again! According to People, Page Six and Entertainment Tonight, Kate's little sister, Pippa Middleton, is pregnant ... that means Prince George, Princess Charlotte and Prince Louis will become cousins. While Pippa and her husband, James Matthews, could not have been happier for the news.

"Pippa and James are excited, it's fantastic news amid a difficult year. The whole family is happy," a source told Page Six.

Pippa and James became parents for the first time on October 15, 2018, when Pippa gave birth to their son, Arthur. Like Kate, Pippa was born in Lindo Wing of St. Mary's Hospital.

Pippa is usually quite reserved about her and James's family life, but she decided to give her fans some details regarding Arthur's rise, in an interview in April 2019 with Waitrose Kitchen magazine. During the interview she revealed that she has been teaching her son to swim since he was four months old and also took him to a children’s gym.

"Teaching my son Arthur to swim when he was four months old has given him confidence and enjoyment in the water," Pippa said at the time. "He is now six months old and swimming is one of our favorite activities. Exercise helps ensure daytime sleep and movement has improved his digestion."

Pippa and James have not yet made an official statement on the news of their second pregnancy.
