Yesterday, Nigella Lawson testified for the prosecution at the fraud trial of her former assistants. The picture she painted of her relationship with ex-husband Charles Saatchi was beyond bleak: it's clear that he was abusive, controlling and manipulative. Under oath, Nigella stated that Saatchi threatened to destroy her public image and spread "false allegations of drug use" about her; she implied that such behavior was part of a long pattern of emotional abuse. She admitted to using cocaine — about six times over a decade ago with her terminally ill late husband, and again, once, in 2010, in order to cope with the "acts of intimate terrorism" Saatchi subjected her to. However, she affirmed that the claims that she was a habitual drug user are "ridiculous."
