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 pretty 19 year old - who plays Bella's BFF 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.
