Nicole Richie and Joel Madden are officially introducing Sparrow! Nicole and Joel's six-week-old son, who looks so much like his big sister did on her first cover, is front and center in mom's arms for his first magazine shoot. The family of four posed for People's newest cover and inside the magazine gushed about their life as a family of four. Nicole said: "I couldn't be happier. The only thing you want is for your kids to be healthy and happy, and they are. I'm right where I belong. I'm glad I had a girl before I had a boy. She just loves him so much." From Joel: "She's very gentle with him." Congrats to the adorable family! Check out all the photos and full interview when the magazine hits newsstands on Friday.
