Rapper Waka Flocka Flame has joined a series of other celebrities in posing nude for an ad campaign for the People for the Ethical Treatment of Animals (PETA) organization. Flame appears tattooed and flexing a bicep while the slogan "Ink, Not Mink" floats next to him. Interestingly, the ad uses splattered blood imagery similar to the rapper's "Flockaveli" album.
