Photoshopped, even a blind man could see that. 
No its not photoshopped. Like I said, practically every Mr. O competitor can show a round belly from angles like that when they are not holding it in. That's why it's silly to use those type of pics when discussing who has the most distended stomach.
So none of them can hold it in at every angle every second of the contest, but the ones with the most distended stomachs are the ones who can't even hold it during poses like the side chest, front relaxed, ab thigh, etc. That includes guys like Kovacs, Fux, the European guy that's posted in this thread (not sure of his name, but I think his is the biggest), Ruhl, etc. Nasser on the other hand showed a very tight midsection in the ab-thigh and the other poses mentioned, and is the only guy under 6 feet at 280 or more lbs to be able to do this.
