Former Gun 'N Roses bassist Duff McKagan his wife, Susan Holmes McKagan, are the latest rockers to strip down for PETA's "Ink, Not Mink" campaign.

"Whether you're a designer or a celebrity, or a stylist, a photographer, I think everyone should share responsibility in bringing more awareness that, hey, [fur's] not necessary, it's out of fashion, it's completely immoral to the animals," said Susan.

The couple's ad comes less than a month after Bengal's wide receiver Chad Ochocinco struck an even more revealing pose (with only a football as a prop) for the campaign.

Check out the full ad below — as well as a video with Duff and Susan talking about their fur-free convictions.
