Amy Adams has given birth to a healthy baby girl -- Aviana Olea Le Gallo.
As RadarOnline.com was first to report, the 35-year-old Julie & Julia star welcomed the seven-pound addition to her family this weekend.
Her fiancé, Darren Le Gallo, was by her side at an undisclosed Los Angeles location for the birth on Saturday.
"Everyone is doing well," a pal of the actress told RadarOnline.com.
"It's very exciting for Amy, Darren and their families.
"They have a large, extended family and all their brothers and sisters are relieved and thrilled that this moment has come for them both."
This is the first child for both parents.
The Oscar-nominated actress and Legallo, who met in 2001 in an acting class, announced last December they were expecting.
Speaking about motherhood recently, Adams said: "I think I really have to meet the person before I'm going to know the name, but I tend to be attracted to more traditional names."
The birth comes nearly two years after the couple got engaged in July 2008.
