Johnny Manziel puts the high in Heisman, according to a photo making the rounds.
The Texas A&M quarterback was photographed kissing college football's famous trophy this past weekend in Vegas ... with the Heisman holding a fat blunt.
2 Chainz would be proud ... but is the photo in question even real?
Manziel says it is 100 percent fake. He just tweeted: "ABSOLUTELY PHOTOSHOPPED. People are always out to get me ... sorry for kissing my trophy."
The pic does sort of look bogus, but then again, Manziel parties hard and posts photos of it on Instagram (remember the casino pic?) so who knows.
