Lacey Chabert isn’t going to be a regular mom, she’s going to be a cool mom.

The Mean Girls star revealed on Twitter Saturday that she is expecting her first child with husband Dave Nehdar.

Sharing a photo of her dog wearing a T-shirt that reads “My mom is having a baby and all I get is this silly shirt,” the actress, 33, wrote.

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

Earlier this month, Chabert was celebrating a different baby when she attended friend Amy Davidson‘s baby shower.

Chabert and Nehdar tied the knot a little over two years ago.
