Nicole Richie ‘ready to expand family’

Nicole Richie and Joel Madden are planning to have another baby.

The two stars already have daughter Harlow, four, and Sparrow, two, together and think a third baby will help cement their relationship.

Although Nicole isn’t expecting yet, they are already making baby plans.

“Joel is thrilled that she’s on board. He even vowed not to tour during the pregnancy or the first three months after the baby is born,” a source told National Enquirer.

Nicole has been busy shooting TV show Fashion Star recently and also creating her clothing lines, while Joel has been in Australia acting as a mentor on their version of talent show The Voice.

They apparently found being apart hard but are now back on track and happier together than ever before.

“For a while, Nicole seriously questioned whether she and Joel would even stay together. I was pretty rough last year. They weren’t on the same page about anything,” the insider claimed.
