Dont know, just a guess. The man and woman we can see that arent Rebbie or Mrs J, are either relatives / cousins, etc or close friends and seem to be a couple. I would say that the person opposite Rebbie who's face we cant see is Rebbies Husband.
BUT... I have to admit, at risking embarrasment and eye rolling from other members, that when I first saw the pic, the first thing I thought of was....
MJ "LAUGHING" at the "MOVIE" like he is probably "LAUGHING" at this "REALITY MOVIE" and whoevers hands and blue jumper that is (even if it is Rebbies husband) is referencing that famous pic of MJ in the Cinema, *which* was also featured on this forum...
Dark hands and Blue Jumper!! Just Sayin...... I know its kinda lame. But its where my brain went. Not sure if the hands and blue jumper link though was just my own brain doing automatic visual association.
But I am officially hoaxessed, so it is more than likely nothing.
