Twilight actress Christian Serratos renounces "wearing carcass[es]" in a new ad for PETA's "rather go naked than wear fur" campaign. We know very little of Twilight other than its Power over Tweens, and we don't at all like that PETA makes its point by getting a naked 19-year-old to risk scraping her bare rump on a tree trunk. Especially because we have no guarantees that those crazy YouTube Twilight people won't shoot footage of themselves running naked through the forest. [OK!]
