'Mean Girls' actress welcomes her baby girl into the world with a heart-melting post.

Gretchen Weiners gave us some our all-time favourite moments from Mean Girls.

Poor Gretchen was always trying to make ‘fetch’ happen:


And, she was really, really sorry that people were so jealous of her:


But, real-life Gretch, Lacey Chabert, has given us our favourite moment so far, with the announcement of her baby girl, Julia Mimi Bella.

While little Julia is obviously adorable, it's her mum's caption that has truly captured our hearts.

"And then my soul saw you and it kind of went, 'Oh, there you are. I've been looking for you.'" Lacey wrote.

"#TBT to the best day of my life. One week ago I became a mom to this precious angel...Julia, you are my heart's deepest dream come true and I love you more than I could ever say. Welcome to this big beautiful world sweet girl!"

See? We told you it was adorable!

We wish the family all the best!
