Nicole Richie And Joel Madden Debut Baby Sparrow

Family, including big sister Harlow, will appear on cover of People magazine.

In September, Nicole Richie and Good Charlotte frontman Joel Madden welcomed their second child, a baby boy named Sparrow James Midnight Madden. On Friday, the new issue of People magazine will feature the happy family, including 2-year-old daughter Harlow, on the cover.

"I couldn't be happier," Richie told the magazine about her family. "The only thing you want is for your kids to be healthy and happy, and they are. I'm right where I belong."

In the issue, Richie dishes that her daughter is absolutely smitten with her younger brother. And she says that she's happy she had her baby girl first. "I'm glad I had a girl before I had a boy," Richie said. "She just loves him so much." Joel added that their daughter isn't rough with her little brother. "She's very gentle with him," he said.

After weeks of speculation around whether or not she had given birth, Nicole made the initial announcement about the arrival of Sparrow on her blog. "In the middle of the night, the very early hours of September 9, 2009, Sparrow James Midnight Madden was born to Nicole Richie and Joel Madden," Richie wrote. "He weighs 7 lbs., 14 oz. Nicole, Joel, Harlow and Sparrow are all doing well. Thank you for all of your good wishes."

In a 2008 interview with MTV News, Madden spoke candidly about how being a parent has helped calm both his and Richie's wild ways. "Being a father is nothing you can plan for," he said. "You've got to take it one day at a time, and there's no manual or anything like that. It's not a conscious change; it just happens to you all of a sudden. We had Harlow, and suddenly our priorities changed. We've both done a lot in our lives, had a lot of fun, but now it's time to be parents, which is a different kind of fun. The priority is our daughter and the kind of family we build around her."
