Liev Schreiber And Naomi Watts Become Parents.

Hollywood stars LIEV SCHREIBER and NAOMI WATTS are celebrating after the actress gave birth to their first child - a week earlier than expected, according to U.S. reports.

The Mulholland Dr. star, 38, gave birth early on Thursday morning at a hospital in Los Angeles with Schreiber by her side, although the couple has not revealed the sex of the baby, reports Life & Style magazine.

A source says, "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."

Watts is said to be resting comfortably in the hospital, close to her Brentwood, California mansion.
