CHELSEA CLINTON holds presser to announce she’s preggers!

Oddly enough, mom HILLARY CLINTON was by her side during the unprecedented TV press conference but not hubby Marc Mezvinsky.

He was in the back of the room, beaming.

Chelsea, 34, made the surprise announcement at an event in Washington that she was hosting with her mother, former Sec-O-State Hillary Clinton.

“I just hope that I will be as good a mom to my child and hopefully children as my mom was to me,” Chelsea said.

Chelsea said she didn’t know the sex of heir to the House of Clinton – yet.

As The ENQUIRER reported previously Chelsea and Marc had been endeavoring to conceive for some time since their marriage in 2010. They previously declared 2014 was going to be "the year of the baby."
