Nigella Lawson shocked at husband's divorce announcement

Nigella Lawson had "no idea" her husband Charles Saatchi was going to file for divorce.

The TV chef is said to have broken down in tears after finding out the 70-year-old art collector - who accepted a police caution for assault after pictures of him grabbing her around the throat emerged last month - was going to announce their separation in a statement to a Sunday newspaper.
