Katherine Heigl Takes a Hit of Grass

Grey’s Anatomy star Katherine Heigl, 29, and fiance musician Josh Kelley, 27, get their grass on at a local health store on Thursday in Los Feliz, Calif.

Kat summoned up the courage and took a shot of wheatgrass and ginger. GROSS! It tastes like… well…. GRASS! Has anyone tried it?

The two left the store with bags full of health-conscious goodies–vitamins, juice shake and a complete internal cleanser (sounds like a bowl of fun!). Kat and Josh headed to Cosmos Cafe for lunch afterwards and then to Heigl‘s mother’s house in Calabasas.
