I highly doubt there is any truth to this considering its coming from a foreign tab site. Doesnt make sense her mom or whoever would even talk to them considering how guarded Em is with his private life. Im sure her mom and the other know that giving statements about them is a big no no. Doubt they would bite the hand them feeds them since Em more than likely supports them all in way or another.
Maybe Em pissed someone off over there and they decided to put this out there to mess with him since its no secret that his private/family life is his Achilles heel.
That said, who cares. its his business. I completely understand why he doesnt want to talk about that kind of stuff, I wouldnt either.
