I agree with this with assuming women in general are pregnant.
HOWEVER.
Simone has publicly stated numerous times that they are actively trying for a baby. She has been in the social media space for a long time now. She knows that when she makes statements like that she is going to have speculation (and in turn engagement). If she did not want the speculation she would have said something by now because I can guarantee that crazy fans would be messaging her about it as well.
She knows what she’s doing.
Also, she LOVES feeling like she misled her audience and "shocked" them with an announcement out of the blue. Last time she even went so far as to lie about drinking alcohol, post misleading photos that showed her doing things that pregnant women shouldn't do just to "throw her followers off" the scent, which she then revealed after the announcement "oh look at all of these clever things I did so you wouldn't know!"
So, fair game, if she wants to make it into a game, she's set a precedent.
