Well, we often see Kojima hanging out with celebs. Here's my theory: Kojima looks like he can't take a lot of alcohol, but in reality he's a beast. He does drinking contests at every party, fills celebs up, so they sign contracts when drunk.
The hair looks much too natural for a video game, so I'm going with a photoshopped picture from a magazine photoshoot or something. Though that doesn't necessarily mean it's fake; it could be KojiPro concept art or something.
