Artist Rose Briccetti created this work for Regretsy, an Etsy metablog, as a commissioned work. The creative brief spotted on Etsy and republished by Regretsy editrix "Helen Killer," demanded "Lady Gaga in one of her bizarre outfits hunched over a unicorn carcass, blood all around her mouth." Go check out the full-sized image at Regretsy, along with the story of how it came to be.
[via BB Submitterator, thanks Eric Harley! Note: an earlier version of this blog post implied that "Helen Killer" issued the creative request herself, and she did not. The language of this post has been clarified.]
