Winter is coming, and Alicia Silverstone wants Portlanders to give up their wool coats.

People for the Ethical Treatment of Animals has announced that a billboard's gone up at Burnside Street and NW 21st Street in Portland showing the "Clueless" actress in the nude. The tag line: "I'd Rather Go Naked Than Wear Wool."

Below you can see the billboard in an image provided by PETA. (We haven't had a chance to run over there and get a look for ourselves.) For those opposed to public displays of nudity, be warned that it shows Silverstone's bare behind, with the front of her torso turned decorously away from the camera.

Silverstone made a PETA video last year in which she talks about the commercial treatment of sheep.

"The biggest thing that people always say to me is, 'They just shear the sheep. They don't kill the sheep," the 41-year-old actress says, before insisting that the process is actually quite violent. "The shearing isn't, like, 'Oh, let me just take your hair off because you need to give me your coat. It's not like that. It's like on the slaughterhouse floor, where there's a conveyer belt. It's going that fast. It's just so fast, the shearing process."

She continues:

"The [sheep are] cut. They're harmed. They get very seriously wounded. And there's no care for them when they're wounded. It's just move on to the next. These are not creatures to the people who are doing this. They're just objects."

The video is below. Another warning: The Silverstone interview is interspersed with disturbing images of violent treatment of animals.

Silverstone is a longtime supporter of PETA. For years the activist organization has drawn attention to its cause by showcasing celebrities in the buff.
