The Julie & Julia (2009) star had her first child - a 7 lb. Baby girl on Saturday, Amy's rep confirmed.

Amy and her fiance, actor Darren Le Gallo of films including "Date Night," named their baby girl Aviana Olea Legallo.
"Mom and baby are home and doing great," the star's rep told Access. "Everyone's healthy and happy."

Amy managed to stay a stylish mom-to-be while she was pregnant, dressing in form-fitting designer dresses on the red carpet and looking fashion fabulous, but she did eventually test out the maternity wear.
