Waka Flocka Flame shows off his birthday suit in an ad for PETA’s “Ink, Not Mink” campaign. Shot by celebrity photographer Robert Sebree, the naked rapper is pictured flexing his bicep and flaunting two strategically-placed diamond chains with the tagline “Be Comfortable in Your Own Skin and Let Animals Keep Theirs.”

The “No Hands” MC joins Pink, Kid Sister, Chuck D, Travie McCoy, Mario, and others who have lent their support to the animal rights organization.

Waka explained why he decided to bare all for the camera. “I love animals. As a kid, I had dogs, fish, iguanas, lizards…,” he said. “So when I heard about PETA, I Googled it and I was like, PETA! I learned about it though. I got a dog, so I wouldn’t want to skin my little puppy.”
