Lacey Chabert is a mom! The Mean Girls actress welcomed her first child, daughter Julia, with her husband, David Nehdar, on Sept. 1. Shortly after giving birth, Lacey shared an adorable photo of her new addition on Instagram, writing, "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!" Lacey first announced her pregnancy back in February with a cute photo on social media. This marks her and David's first child together after they tied the knot in 2013. Congratulations!
