Congratulations to former First Daughter Chelsea Clinton and her husband

Marc Mezvinsky on expecting their third child.

Clinton tweeted the news on Tuesday.

“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 tweeted.

They are already parents to couple two children, 4-year old Charlotte, 4, and 2-year old Aidan, 2.

The new arrival will be here later this year!

Clinton wed Mezvinsky in 2010 and became mom to Charlotte in 2014 and Aiden in June 2016. 

Congrats!
