Congratulations to Amanda Seyfried!
The "Mean Girls" star gave birth to her first child, a baby girl, with husband Thomas Sadoski, Sadoski's rep confirms to ET.
"I'm ready," the 31-year-old actress confessed, while Sadoski -- who announced the two had secretly married just last week -- gushed about becoming a dad.
"I'm blown away by her every day," the 40-year-old actor said of Seyfried.
"She does look about ready to pop. It's a pretty amazing thing. I just get to sort of hang back and watch it all happen," Sadoski added. "That's the great joy for me, trying to learn as much as I can -- try to stay out of the way and not screw anything up too much."
