For a good cause of course.

'Twilight' actress Christian Serratos is the latest and youngest celeb to take her cloths off for PETA's new ‘I’d Rather Go Naked Than Wear Fur’ anti-fur ad.

The 19 year old starlet appears butt naked in amongst the trees of a misty forest as she begs fans not to wear fur.

I do not know if she will get all her fans to not wear fur, but she might give the boys a reason to watch 'New Moon.'
