Chelsea Clinton pregnant

Former - and potentially future - First Daughter Chelsea Clinton made the big revelation last Thursday: She's pregnant.

She announced the news during a speech in New York City with her mother, Hillary Clinton, at her side.

"Marc and I are very excited that we have our first child arriving later this year," she said at the Lower Eastside Girls Club, at the end of a Clinton Foundation event dedicated to empowering young girls.

Clinton did not say if she and her husband, Marc Mezvinsky, are having a boy or a girl. But she later tweeted that her due date is sometime this fall.

"I certainly feel all the better, whether it's a girl or a boy, that she or he will grow up in a world full of so many strong, young female leaders," she told the audience full of young women. "So thank you for inspiring me."

future generations

Grandmother-to-be Hillary Clinton connected the announcement to the focus of the day's event, telling the crowd that she is not only excited for her family but for the future generations who may not have to face the same glass ceilings as she did.

"Obviously, we are very excited about what's happening in our family," she told the young women. "But we're also very excited, because of what we're 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, and try to make sure there are no ceilings that are stopping you from going as far and as high and as fast as you can."

"I just hope that I will be as good a mom to my child - hopefully, children - as my mom was to me," Chelsea replied.

Bill and Hillary Clinton both responded on Twitter shortly after the announcement Thursday afternoon.
