don't buy that he didn't notice either.
mr.o knows his own physique
Here is the thing. We have no proof that he took the pic, put it through a filter to make it "grainy" and photoshopped his waist/obliques and arms.
What we have is two different pics. And from what we know, he hasn't done this before, plus he is off season. So, the question is, "why would he do this now?", we do know that he is comfortable with his "bloofiness".
Instead of us jumping to conclusions, like very bad detectives, and then running with what we want, we need to instead of come up with logical answers/conclusions using the info that we have.
