Rules of Engagement star Oliver Hudson and actress Erinn Bartlett are adding another baby to their family, a close friend of the happy couple tells Life & Style.

"It's early on in the pregnancy," adds the friend. "Erinn is a few months along."

The two, who met at a party in 2000, dated for six years before tying the knot in June 2006. Erinn gave birth to a baby boy, Wilder Brooks Hudson, on Aug. 23, 2007. The couple's new addition is expected to arrive sometime in early 2010.
