Just a few years back, Nicole Richie was literally hell on wheels. (The whole driving down the wrong way on the highway while intoxicated thing springs to mind.) Now, she and her rocker beau Joel Madden have settled down — establishing a charity called Richie-Madden Children’s Foundation and raising a baby girl named Harlow. But I have to say, I was really shocked to see the happy couple exiting a store today with Seventh Generation Chlorine-Free Diapers. She’s come a lot further than I expected, joining the ranks of green guru Julia Roberts, by using these diapers, which are free of dangerous toxins and help reduce the amount of dioxin polluting air, land and sea.
