Bill and Hillary Clinton are about to take on a new and exciting rolegrandparents! Former First Daughter Chelsea Clinton announced today that she’s pregnant, and is due later this year. She broke the news alongside her mother today, while the pair were speaking at an event in New York City for the Clinton Foundation’s “No Ceilings: The Full Participation Project,” which seeks to empower women globally.

This will be the first child for Clinton and her husband, Marc Mezvinsky, who married in 2010. Clinton revealed that the couple does not know if it’s a boy or a girl. The news of Clinton’s pregnancy doesn’t come as a shock, as she previously stated that they were looking to start a family this year. Congratulations to the expanding family!
