Nicole Richie has given birth to her second child, a baby boy.

Nicole and her baby daddy Joel Madden of Good Charlotte named their baby pirate new son Sparrow James Midnight Madden. Sparrow joins little sis Harlow Winter Kate in the newest generation of LA socialites.

The couple announced the happy news on Richie's website:

"In the middle of night, the very early hours of September 9, 2009, Sparrow James Midnight Madden was born to Nicole Richie and Joel Madden. He weighs 7 lbs. 14 oz. Nicole, Joel, Harlow and Sparrow are all doing well. Thank you for all of your good wishes," they wrote.

Joel told People in August of his gratitude for his growing family. "We're very, very blessed," he said. "We've already had one healthy kid, and that's all you can ask for as a parent -- healthy kids."

Richie, 27, and Madden, 30, are committed romantic and parenting partners but have not announced any plans to wed.
