The 29-year-old Black Swan actress is expecting her first child with fiancé Benjamin Millepied. She told The Daily Telegraph that she is able to lead a relatively normal life because she is not 'harassed' by fans wherever she goes and thinks that is down to her good girl image.
'I'm not exactly a bad girl... it's not important that strangers know who I really am,' she explained.
'I go to the mall at Christmas time. I go to the movie theatre on Friday nights. I'm pretty anonymous. I sometimes get recognised, but not harassed.
'So I feel very left alone because of that good girl image. Maybe people get bored by it and that's great.'
