Kristen Johnston has become the latest celebrity to pose nude for PETA. The former "3rd Rock from the Sun" star - who recently caused concern with her drastic weight loss - poses as Lady Godiva, naked and astride a horse, in the photograph which debuted in New York's Central Park Thursday.
The 41-year-old actress has joined forces with the animal rights group to campaign against the horse-drawn carriage rides on offer in New York.
