It's a very big week for Ellie Kemper—and not just because Season 2 of her hit series Unbreakable Kimmy Schmidt hits Netflix April 15: The actress announced her pregnancy Wednesday on the Tonight Show. Kemper and her husband, Michael Koman, are expecting their first child together, she revealed.

The Princeton grad, who formerly starred on The Office, showed off her budding bump in a white shift dress and told Jimmy Fallon and the studio audience: “I have big news, I’m pregnant!”

The host leaned over and said, "Hi, baby!" and presented the expectant mom with the perfect gift: a pint of her favorite Ben & Jerry's ice cream, The Tonight Dough.

Kemper and her husband, a former writer for Late Night with Conan O'Brien, have been married since 2012.

Earlier this year the actress told InStyle that she has plans to write a book, following in the footsteps of her Unbreakable boss Tina Fey and former co-star Mindy Kaling. “I’m putting it out there in the universe so I make sure that I follow up on it,” she said. Kemper says she “would hope to do maybe a little mix of some autobiographical stories and then some made-up stories.” It sounds like she may have to add another, very small character into the mix!

Watch her announce the good news on the Tonight Show in the above video. Congrats to the parents-to-be!
