Jessica Alba, wearing a Sylvie Rose Bar ring by Dana Rebecca Designs, was given the Green Parent Award for founding The Honest Company. We always talk about Jessica's amazing sense of style, but she has a handle on more important issues, as well. The Honest Company offers natural and eco-friendly products for your home, like non-toxic cleaning products, and your babies, like natural diapers and organic wipes. Jessica's hubby Cash Warren was by her side to help celebrate!
