Nigella Lawson reportedly used to lock herself in a secret bunker in her 27 million dollars Chelsea mansion, which she nicknamed 'The Cell'.
The celebrity chef's former housekeeper Francesca Grillo has revealed that she would lock the door and tell everyone to not bother her, except for one of her housekeepers who brought her tea, News.com.au reported.
The Italian aide added Lawson was very demanding and it felt like nobody could win with her.
