So she deliberately adopts the 'smacked arse' expression? That says it all, really.
She was the one bleating on twitter about people being cruel and threatening to blame them if she had a miscarriage. Sounds pretty stressed out to me. Then there's the court case. She also looks rough (not helped by her insistance on frowning and squinting). She certainly doesn't appear to be someone who isn't stressed.
Of course she's stressed, she brings it all on herself, why does she even go on Twitter and say stuff like that, what does she expect?
