Publicist Brad Cafarelli tells The Associated Press in an e-mail that "Matthew and Kate welcomed a healthy baby boy" Saturday in Los Angeles. The birth gives a brother to Hudson's other son, 7-year-old Ryder, whose father is Black Crowes lead singer Chris Robinson.

And it means Hudson's mother Goldie Hawn is a grandmother again. Hudson and Robinson divorced in 2007. She and Bellamy got engaged in April. The 32-year-old actress was nominated for an Oscar for 2000's "Almost Famous," and has since appeared in several romantic comedies including "Fools Gold" and "How to Lose a Guy in 10 Days."
