What is Heigl doing at their house?
She is the ex-wife, so how does she come to stay with them? Or is she just visiting all the time?
shareSee, the movie hasn't been released yet. So, at this point in time, we don't know anymore than you do.
Hope changes everything.
The trailer suggested she had part-time custody of their son, so that would explain her being around the house in the beginning
(ah, I'll miss these pointless comment boards).
