Nicole Richie Introduces Baby Sparrow!

Just a short month and a half after giving birth, Nicole Richie decided to introduce the world to her adorable newborn son. Sparrow James Midnight Madden, Richie’s second child with Good Charlotte frontman Joel Madden, was born on Sept. 9, weighing in at 7lbs 14oz.

Both mami and baby are doing well. Although the couple admits to being sleep deprived, they are over the moon with the latest addition to their family. "I couldn't be happier," Richie tells People about her role as mother of two. "The only thing you want is for your kids to be healthy and happy, and they are. I'm right where I belong."

And Nicole's not the only one who is ecstatic about Sparrow, it seems Richie and Madden's 21-month-old daughter Harlow is also fawning over her baby brother. "She's very gentle with him," says proud papi Madden. "I'm glad I had a girl before I had a boy," adds Richie. "She just loves him so much."
