Holly Madison may be taking Las Vegas by storm, but the former Playboy model and star of The Girls Next Door wasn’t too busy to pose for peta2’s “Save the Seals” ad series.

Knowing that tens of thousands of seals, many of whom are still babies, are shot or bludgeoned to death for their fur each year in Canada’s seal slaughter, Holly couldn’t sit idly by, so she decided to get involved and help spread the word.

Holly, who previously posed for not one but two naked anti-fur ads for PETA had this to say about the seal slaughter: “I started hearing about the seal hunt in Canada over the last couple of years—it’s been pretty heavily publicized. I wasn’t aware that the seal hunt is as brutal as it is until I started getting more information from PETA, and it’s pretty shocking, actually.”
