Nicole Richie may have ended her hard-partying days, but that doesn't mean she's prepared to live like normal folk. Richie and her husband, Joel Madden, got into an argument on Twitter about her home décor habits -- specifically relating to pillows. Madden had tweeted, "Do you ever look at your credit card bill & ask your wife how the hell she could spend 3 thousand dollars on pillows?" No, Joel. We have never done that. It's only you and your Scrooge McDuck-wealthy friends who do that.
