Speaking about her decision to strip off for the 'I'd rather go naked than wear fur' campaign, Gemma said: "Like PETA, I believe that beauty comes in all shapes and sizes.
"You don't have to be a size 8 to feel beautiful, but you do have to be comfortable in your own skin. And that means letting animals keep theirs – not killing them for their fur."
Gemma's not the first celeb to strip naked for PETA...
