Cameron Diaz was dressed down for a day of shopping with a female pal in West Hollywood on Saturday. She wore jeans and a gray sweater as she popped into a store to buy a few goods. She may have been out looking for something for Gwyneth Paltrow's son, Moses, as she was spotted at the actress's star-studded birthday party for her son later that day. Other celebrity attendees at the party included Gwen Stefani, Kate Hudson, and Joel Madden, who took over dad duties with Harlow and Sparrow while his wife, Nicole Richie, went on a St. Barts bikini vacation with friend Jessica Alba.
