It’s another boy for Naomi Watts.

The star and partner Liev Schreiber welcomed their second child, a son, on Saturday.

“They had a baby boy yesterday,” a rep for the 40-year-old actress confirmed to Access Hollywood on Sunday.

In Touch Weekly first broke the baby news on Saturday night.

The couple’s first child, Alexander Pete, was born on July 25, 2007 – and according to papa Liev, preparing him for a sibling hasn’t been easy.

“Naomi’s been teaching him ‘Kiss the Baby,’ which basically involves him going up to kiss the bump,” he told AccessHollywood.com’s Laura “Dish of Salt” Saltman at the “Defiance” junket last week. “I don’t think he knows yet that there’s something lurking in there that’s about to seize the spotlight from him forever.”

And while some stars take time off for their kids, Liev said his oldest son, whose nickname is Sasha, has influenced his choice of roles, as well.

“It’s… starting to occur to me,” Liev, who plays Sabretooth in next May’s “X-Men Origins: Wolverine,” told Laura. “I really thought of Sasha when I said yes to ‘Wolverine.’ I thought it would be fun for him to see his dad acting like a giant mutant game cat.”

But, he added, it may be a while before his kids are ready for the movies.

“Sasha’s 16 months old and all he wants to do is play the game where I pretend I can’t see him,” he said.
