Greene is an avid artist who often creates self-portraits to help himself build and maintain his ideal physique.   In August 2011, he exhibited some of his work to the public; at the exhibition, he stated, "As a professional bodybuilder, I'm a master sculptor. The art show made me realize that I've always been an artist: my medium the human physique. My life is what I make it, just like the art I've produced on canvas and on stage. This art show makes this statement. I'm celebrating some personal accomplishments and my own artistic expression."
