We spotted Nicole Richie walking back to her car after having lunch with a friend at Sushi Nozawa in Studio City yesterday. She wore a loose, flowing top and carried a leather fringe purse.

She was also spotted leaving the gym in a large t-shirt. Is she hiding a baby bump?

Nicole finally wed the husband of her children, Joel Madden, in December. The couple has a 3-year-old daughter, Harlow Winter Kate Richie-Madden, and a 1-and-a-half-year-old son, Sparrow James Midnight Madden.
