According to her son, Cilla Black died laughing at Jeremy Kyle and drinking champagne.
As someone that was supposed to have remembered " where she came from" there are so many anecdotes about what a diva she was. From the way she treated cabin crew, to the time she showed no empathy to the family of a motorcyclist her son had killed in a crash (she was more worried about if he would go to prison) this is just another example of how she saw herself as being above the rest.
Laughing at people who obviously have issues, be it in relationships or in life in general isn't pleasant. I just don't get the public fawning over her when she sounds like an unpleasant person. Perhaps it is just another case of celebrity worship.
