Chelsea Clinton’s family is about to become a party of five.

The author and daughter of former President Clinton and 2016 Democratic presidential nominee Hillary Clinton announced Tuesday that she’s pregnant with her third child.

Marc and I have loved watching Charlotte be such a wonderful big sister and we’re excited to watch Aidan become a big brother! We cannot wait to meet our newest addition later this summer.

Clinton’s daughter, Charlotte, with husband Marc Mezvinsky is 4, while their son Aidan is 2 years old. The pair tied the knot in 2010.

In 2018, Hillary Clinton told ITK that the best thing about losing the election to Donald Trump was getting more face time with her daughter’s now-growing brood. 

“I get to see them all the time,” the former secretary of State said. “I get to spend a lot of time with them.”
