Nicole Richie, who welcomed her second child, son Sparrow, into the world last month, said she "couldn't be happier" with her life as a mother-of-two.
"The only thing you want is for your kids to be healthy and happy, and they are," Richie, 28, told People. "I'm right where I belong."
Richie also has a daughter, 21-month-old Harlow, with her boyfriend, 30-year-old Good Charlotte front man Joel Madden.
She said that young Harlow has been an excellent sister to her six-week-old brother Sparrow, who was born September 11.
"I'm glad I had a girl before I had a boy," Richie said. "She just loves him so much."
