I'm sorry but she really is obsessed... Their season of Survivor was filmed over a year ago and she is still bashing him on Twitter and now dragging his kids into this which is just wrong and nasty.
I'm not saying he was right to treat her the way he did on the show but the things she is writing are really personal and cruel and totally unnecessary. It makes me think there was more that she did to fuel the hatred she got from her tribe that we did not see.
