Besides auctioning herself as a lunch date to benefit farm-animal protection group Farm Sanctuary, and being named a Sexiest Vegetarian by PETA, Bell starred in this almost-too-cute-to-be-true GAP ad encouraging people to vote on behalf of “those who can’t talk and those who can’t write” (birds, bees, flowers, trees, icebergs, seas, etc.). We won’t be forgetting her anytime soon.
