Nicole Richie and her husband Joel Madden took their youngest, Sparrow, out for lunch yesterday in LA. Nicole was sporting workout gear, perhaps after clocking a workout at Tracy Anderson's nearby studio, where she is a regular. The star is back in LA with her young family after stepping out with her fellow fashionable celebrities at the Met Gala on Monday night in NYC, where she rocked a glamorous, old Hollywood look on the red carpet. It was the latest event in what has been a style-focused several weeks for the designer and mother of two. She also took a trip to Florida to host a trunk show for her latest Winter Kate collection, toasted her friends Mary-Kate and Ashley Olsen at a party for their TEXTILE Elizabeth and James line, and dished to Teen Vogue about her impressive collection of sunglasses, which she says tops 200 pairs!
