Naomi Watts gave birth

A source said, "Naomi was planning on giving birth next week-- her due date was early August -- but since she insisted on delivering naturally, she knew there was a chance she would have the baby before the due date. That's what wound up happening."

"This is a dream come true for both of them and they've done everything in their power to make it as special as possible, right down to staying in the dark about the baby's sex right up until Naomi gave birth."

UPDATE - They had a boy weighing in at 8 lbs., 4 oz. They have named him Alexander Pete Schreiber.
