Lacey Chabert isn’t a regular mom—she’s a cool mom. The 33-year-old actress, known by girls everywhere as Gretchen Wieners from Mean Girls, just welcomed her first child with her husband David Nehdar, a daughter named Julia Mimi Bella.

The actress announced the news on Instagram with an adorable photo of her baby girl—who has a full head of brunette hair much like Mom—swaddled in a pink blanket. “#TBT to the best day of my life. One week ago I became a mom to this precious angel,” she wrote on Thursday. “Julia, you are my heart’s deepest dream come true. I love you more than I could ever say. Welcome to this big beautiful world sweet girl!”

Chabert first announced her pregnancy in February with a hilarious picture of her pooch wearing a tee that reads, “My mom is having a baby & all I get is this silly shirt.”

“Kitty does seem as excited as we are about this … I’m pregnant!!!! My husband and I are thrilled & so thankful,” she wrote.

Throughout her pregnancy, the actress looked radiant, swathing her baby bump in a series of fitted frocks.
