Lacey Chabert is going to be a mom--- that’s so fetch!

The Mean Girls actress took to social media to announce her pregnancy over the weekend. She tweeted a picture of her dog wearing a shirt that said “My mom is having a baby and all I get is this silly shirt.”

“Kitty doesn't seem as excited as we are about this...I'm pregnant!!!! My husband and I are thrilled & so thankful,” Chabert wrote.

Chabert married Dave Nehdar in December 2013 in Los Angeles. This is their first child together.

Chabert recently celebrated another pregnancy at her friend Amy Davidson’s baby shower. She posted a picture from the party with Davidson and mutual friend Kaley Cuoco.

"So happy to have been a part of @amy_davidson baby shower!" Chabert wrote. "It was a beautiful day. @normancook thank you for hosting us! Also a huge shoutout to @goodcarmastudio for planning such a lovely party!"

Chabert thanked her fans for their support after her big announcement.

“Thank you all so much for the sweet messages. It means a lot!” Chabert wrote with a kissy face emoji.
