Hollywood at late-night hot spots like Hyde and Les Deux. But when in search of a slightly more elusive group of celebrities in broad daylight, the stalkerazzi hightail it to the Brentwood farmers’ market, the favorite spot for locally grown produce. Sure, there’s a Whole Foods just down the street, but stars like Marcia Cross and Jessica Biel prefer to browse al fresco for fruits, veggies and flowers. Naomi Watts had the right idea pre-pregnancy, bringing along her own Sherpa, boyfriend Liev Schreiber. These days she makes it a family affair, complete with new baby, Alexander. Of course, there are two things Jennifer Garner and Blythe Danner need not add to their market shopping list: violets and apples.
