Christian Serratos shows off her PETA ad

Braving the cold weather, Christian Serratos shows off her PETA ad on M Street in Georgetown, Washington, D.C., on Saturday afternoon (December 19).

The 19-year-old New Moon actress was on hand to celebrate the opening of “Naked Ambition: 20 Years of PETA’s Sexy Celebrity Ads.” The special Govinda Gallery exhibit will expose thousands of Georgetown holiday shoppers to PETA’s fur-free, vegan message through a series of provocative window displays. The exhibit will be open to the public free of charge on M Street throughout December.
