Kristen Johnston gets her PETAs out

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 yesterday (20.11.08).

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.

She said: "I was blown away by how these horses live, or actually I should say, don't live. I'd say to tourists who are considering coming to New York, there's so much amazing stuff about Manhattan. Oh my God, just take a walk! And I hope within the next year that there are no more carriage horses."

The stunning shot was taken by renowned photographer Joseph Cultice.

Other beauties who have shed their clothes to raise awareness of animal rights issues include Alicia Silverstone, Eva Mendes and Christina Applegate.
