Congratulations, Chelsea Clinton!
The 35-year-old took to Twitter on Monday, Dec. 21 to announce that she is expecting her second child with husband Marc Mezvinsky — and we can't get over how adorable the pregnancy announcement is!
"Next summer, Charlotte is going to be a big sister!" she captioned the adorable snapshot of their one-year-old daughter. "Feeling very blessed & grateful this holiday season."
The former first daughter — she is the only daughter of Hilary and Bill Clinton — welcomed Charlotte with her investment banker husband, 37, in September 2014. The duo tied the knot in July 2010.
