An errant breeze under a roomy ensemble or a sign of an impending stork visit? This week, a host of armchair obstetricians began speculating about the contents of Nicole Richie's belly after she was snapped sporting what may or may not be a slightly swollen midsection. The evidence, such as it is, includes this photo of her wearing a comfy summer dress during a trip to a Los Angeles park with 3-year-old daughter Harlow and 18-month-old son Sparrow, and this pic of her exiting a gym in an oversized sweatshirt. So, could Nicole and husband Joel Madden be adding to their adorable brood, or is she just the latest victim of Hollywood's overactive womb watch? Turns out it's the latter. In a statement to Us, Richie vehemently denied the pregnancy talk.
