I honestly don't believe the whole pregnancy situation was real. I hope I am wrong, in that I hope I have tragically misjudged an innocent couple. But unfortunately some people are willing to cross any line to go viral. And I wouldn't be surprised if it came out the whole pregnancy was faked.
It annoyed me that the guy claimed God "forgave him" for his Ashley Maddison account. I'm not as religious as I used to be, but it pisses me off when people use God as an exemption from their faults. If I go out and murder several people, and then claim God thought it was okay (I know these are radically different situations, but same principle), some people would have issues with that.
So in my opinion I think they are just trying to be the next "viral" couple. Along the lines of that family who convinced the news that their son was in a weather balloon.
The whole situation, real or not, does not belong on YouTube. It's like they're trying to cash in on whatever they can with it, and that just doesn't sit right.
