Alicia Silverstone is so eco-conscious, she’s endorsed an environmentally friendly vibrator. The actress picked up an eco-friendly self-pleasure product on OpenSky.com, we’re told. The Leaf Vibrator is “inspired by nature, and with a wide range of shapes that are sure to please.” It’s also chemical-free, uses rechargeable batteries and comes in recycled packaging. Perhaps the toy is a prop for Silverstone’s new project — a Broadway play, “The Performers,” about the adult film industry.
