Nicole Richie and Joel Madden love being parents so much they're going to have another baby, barely one year after having their first daughter Harlow Winter Kate Madden, who was born on January 11 last year.

"What's better than winning an Oscar?" a very enthusiastic Madden wrote on his band Good Charlotte's website. "I am so happy to tell everyone that Harlow is going to be a big sister!"

"God has truly blessed my family. Hope you're all feeling as good as I am right now," he added.

Joel was equally excited about becoming a father when he and Richie announced her first pregnancy on "Good Morning America" in late July 2007.

In an October cover story for People, Joel sounded eager to expand his young family with another child.

"Eventually we'd love to have more kids," he said at the time. "Especially if they can all be as easy and wonderful as Harlow!"

At the time, Nicole was not so easily convinced! "Right now? Oh my God, I need a nap first," she joked.

The couple, who have been dating for almost three years, have yet to disclose when Nicole is due. Most recently, Nicole was spotted in New York with her daughter shopping for a new apartment.

Before Nicole gave birth, the two some twosome established the Richie-Madden Foundation, a charity that supports needy families and children.
