Lacey Chabert—AKA Gretchen Wieners from Mean Girls, whose hair is full of secrets—just gave birth to an extremely cute baby girl, she announced on Instagram. The baby's name is apparently "Julia Mimi Bella," which certainly does sound like something a Plastic would name her child.

The caption reads:

And then my soul saw you and it kind of went, 'Oh, there you are. I've been looking for you.'" #TBT to the best day of my life. One week ago I became a mom to this precious angel. Julia Mimi Bella. 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!
