Chelsea Clinton, 34, is pregnant with her first child with husband Marc Mezvinsky.
Chelsea announced the news Thursday at the Clinton Foundation's No Ceilings: The Full Participation Project event, which seeks to empower women globally.
"Marc and I are very excited that we have our first child arriving later this year," she said. "I certainly feel all the better whether it's a girl or a boy that she or he will grow up in world filled with so many strong female leaders."
Former President Bill Clinton was quick to respond to the happy news:
Excited to add a new line to my Twitter bio...grandfather-to-be! @hillaryclinton and I are so happy for Chelsea and Marc!— Bill Clinton (@billclinton) April 17, 2014
Chelsea and Marc have been married since 2010.
