Angelina Jolie wore fake fur when she was on the set Salt because she is an animal lover.
PETA wrote in their blog, "Yes, Angelina Jolie was spotted wearing what appeared to be a chinchilla-trimmed hat and cape on the set of her latest movie, spurring one of the best blog headlines that we’ve seen all week. But our L.A. staffers were on it faster than Liza Minelli can open a bottle of Scotch, and they’ve received word from the film’s publicist that (phew!) the chinchilla is actually synchilla. We knew sweet Angelina to be an animal lover who never wears fur."
"Don’t worry, Ange, we knew a big-hearted U.N. Goodwill Ambassador like yourself would never wear the skins of achingly adorable little animals who go “coo, coo” when they’re excited and like to hold things in their cute little pinkish-gray hands. We just knew it."
