The 'I'm A Celebrity' star has stripped off and flashed the flesh to help PETA raise awareness of the use of exotic animal skins in the fashion trade.
The ad, which was shot by celeb photographer Trevor Leighton, sees the newly crowned FHM Sexiest Woman in the UK, posing next to the words 'Exotic skins belong in the jungle. Leave wildlife out of your wardrobe'.
Helen, who launched the campaign in London's Covent Garden earlier today, said: "Spring is the perfect time to clean the cruelty from our closets.
"I know when people see PETA's video, they won't want anything to do with the exotic-skins industry and will join me in leaving wildlife out of their wardrobes."
