Naomi Watts had a baby boy Wednesday at 3:59 p.m. in Los Angeles. Alexander Pete Schreiber weighed in at 8lb, 4oz, and 22 1/2 inches long. He is the first child for Watts, 38, and her boyfriend Liev Schreiber, 39.

While most everyone assumed she was past her due date, Life & Style quotes an insider who says that the baby was actually early:

“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.”

Naomi’s rep say they’re “doing great” and that the new parents are “ecstatic.” Congratulations to Naomi and Liev, that’s great news and we can’t wait to see their new arrival!
