Susan Holmes McKagan and Duff McKaganBassist Duff McKagan of Guns N' Roses and Velvet Revolver fame recently disrobed alongside his wife, Susan Holmes McKagan, as part of PETA's "Ink, Not Mink" anti-fur campaign.

The rock couple are not the only stars to pose for the cause -- musicians Dave Navarro, Tommy Lee and Linkin Park's Chester Bennington have also shown their tattooed bods for the campaign.

Susan told PETA, "I think we should know better than that. 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."
