Naked Celebs: Helen Flanagan, Kelly Brook, Jodie Marsh, Pamela Anderson Strip For PETA (PICTURES)

Well, apart from not exactly being a shy and retiring bunch, they've all stripped naked to raise awareness of animal rights for the charity, PETA.

PETA (People For The Ethical Treatment Of Animals) are a UK-based charity dedicated to protecting the rights of all animals, and have persuaded a whole host of celebs to strip off over the years.

Whether it's Pamela Anderson encouraging us to go vegetarian or Helen Flanagan's recent campaign to raise awareness of the use of exotic animal skins in the fashion world, PETA always manage to get their message across thanks to a bit of naked celeb flesh.
