The Clintons are going to be grandparents -- Chelsea Clinton is expecting her first child later this year.
Chelsea Clinton, who married Marc Mezvinsky in 2010, made the announcement Thursday during an event in New York with her mother.
"Marc and I are very excited that we have our first child arriving later this year," she said. "I just hope that I will be as good a mom to my child, and hopefully children, as my mom was to me."
Chelsea Clinton, 34, delivered the news as she and her mother hosted "Girls: A No Ceilings Conversation," which is part of their project that works to advance progress for women and girls around the world.
The former New York senator and secretary of state, who is considering another presidential run in 2016, said she is thrilled.
"It makes this work even more important because we've made a lot of progress," said the former first lady.
"Obviously we are very excited about what's happening in our family," she said. "But we're also very excited because of what we are doing that we hope gives confidence and support to so many of you across our country as you make decisions about the lives you want to lead."
Later Thursday, the Twitter account for Bill Clinton posted a tweet that said "Excited to add a new line to my Twitter bio ... grandfather to be! @hillaryclinton and I are so happy for Chelsea and Marc!"
