Lacey Chabert gave birth to her first child last week and on Thursday, Sept. 8, she shared the first picture of her little one via Instagram.

The Mean Girls star and her husband, David Nehdar, welcomed a daughter who they named Julia Mimi Bella Nehdar on Sept. 1.

"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 ????," Chabert captioned the adorable photo of her baby, adding, "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!"

Us Weekly noted that the actress and Nehdar tied the knot in 2013 and announced last February that they were going to be parents.

Congrats on the new addition to the family!
