Life’s a picnic for Mena Suvari, Kate Mara, Emma Roberts and Busy Philipps, who all joined Tracy Reese to celebrate the launch of the designer’s new picnic basket for Clos du Bois wines. “It’s great for picnics in the park, on the beach, in the backyard or even in your kitchen,” Reese told InStyle.com of the outdoorsy item, available now for $135 at closdubois.com. “The basket can even double as a tote!” Plus, see Nicole Richie, Michelle Williams, January Jones, and more stars at yesterday’s biggest parties in the gallery.
