Nicole Richie and Joel Madden talk about expanding their family

Nicole Richie and Joel Madden are talking about expanding their family.

Last year Nicole, 27, told OK! she hoped to have "three girls and twin boys." Would she adopt? "Definitely, I'm adopted," she said. Now Joel, 29, is moving on over to Nicole's point of view.

"I'm definitely not against adopting," the Good Charlotte member told OK! "I went to Central African Republic and fell in love with the place. If I was going to adopt, it would probably be from there. Nicole and I are very happy and eventually we'd love to have more kids, especially if they can all be as easy and wonderful as Harlow!"
