Justin Gaston, Miley Cyrus’ ex-BF, is joining his If I Can Dream castmates for the latest anti-fur campain … If You Need Fur To Keep Warm, You’ve Got Problems.

Gaston, along with Giglianne Braga and Ben Elliott, looking fit and fabulous, joined the cause after watching a graphic video showing animals being skinned alive for their fur.

Braga tells PETA, “I don’t understand how people can do that, really. Just torture and kill like that for the sake of fashion.”

“This is definitely the … raciest thing I’ve ever done, but it was for a good cause,” adds Gaston.
