PETA / . 1 / 3

"Twilight" star Christian Serratos has become the youngest star ever to peel off for Peta's iconic 'Rather Go Naked Than Wear Fur' ads by posing provocatively against a tree in a misty forest.

The 19-year-old, who plays Angela in the film franchise, brings new blood to the animal rights campaign.

The vegetarian star says, "I've always been opposed to slaughtering, eating and wearing carcasses."

Serratos joins a growing list of celebrities who have starred in PETA's anti-fur ad campaigns -- they include Charlize Theron, Eva Mendes and Roselyn Sanchez.
