Nicole Richie was prancing around Beverly Hills yesterday in a great mood as she ran errands and showed off her growing belly, in what appears to be her new favorite frock, having worn it several times this month. Although it has yet to be confirmed, we hear that Joel Madden popped the question to his pregnant girlfriend and the couple is now engaged! There is no ring on that dainty little finger of hers but hopefully we'll get a look at the rock soon!
