Why does everybody seem obsess with Hugh's wife?

It is envy and jealousy. Everyone wants to get Hugh, but can't get him. And she can.

Because some fans have delusions/dreams/wishes (strikeout unneeded ones) about Hugh's relationship with Lisa, so they have to control whether he is or isn't still married.

Apart from the fact she's the LUCKY woman who IS in fact his wife, I think it's because there is very little we actually know about her.
All we do know is what Hugh has divulged (which is not much) and other generic info. The fact that she has an aversion to cameras of any sort, makes her interesting because we are not flooded with images and info about her at every turn.

I think everyone checks up on their movie star 'crush' spouses. Envy, jelousy? Both. Lol, I think it's funny but I do the same thing! :D I just want to know the compatition. lol, just kidding. :P
