Naomi Watts and Liev Shreiber Welcome Baby Boy!

In celebrity baby news, Naomi Watts and Liev Schreiber gave a warm welcome to a healthy son in New York City on Saturday (December 13).

Keeping her release short and sweet, a rep for the 40-year-old Watts told E! News, "I can confirm that Naomi and Liev had a baby boy yesterday."

Although still unmarried, the couple have been together since 2005 and have one previous son, Alexander Pete, who was born on July 25, 2007.

Describing her pregnancy to People magazine back in May, Watts said she was "just being relaxed and moving at a much slower pace and enjoying it. I'm just really happy to be pregnant."

More details about the couple's newest addition are expected to be released later this week.
