Clearly he was hiding it just as Chandella was hiding her photo shoot. The UFC can only do so much. If they knew this they wouldn't have had him on the cast imo. Now that he is on it and the news has been released, I guess they just decided to roll with it.
I don't anticipate any porn stars crossing into MMA in the future lol. War Machine being the exception going the opposite route lol
He wasn't hiding it, it got brought up after he beat Varner at that HDNet show a few months ago.
