Fallen celebrity chef Nigella Lawson has denied using cocaine regularly. 'I promise you...regular cocaine users do not look like this,' she said.  Nigella Lawson’s home was akin to a high-end coke den, one of her former personal assistants testified Thursday, contradicting the disgraced celeb chef’s own claim she was no coked-up cook.  Elisabetta Grillo, 41, said on the stand that she saw “white stuff” on CDs, rolled up cash and credit cards while working for Lawson, 53, when she was married to her deceased ex-husband John Diamond as well as her ex-husband, hot-shot art dealer Charles Saatchi.  “I was cleaning the house, and I noticed little packets on top of the loo — the toilet, and I opened it...and I saw white powder," said Elisabetta Grillo, according to The Mirror, adding that she saw evidence of the drug roughly “at least every three days.”  RELATED: NIGELLA LAWSON A ‘HABITUAL CRIMINAL,’ SAYS LAWYER IN THEFT TRIAL AGAINST EX-ASSISTANTS BLAMING HER  That calls into question Lawson’s own claim last week she wasn’t a regular drug user.  “I promise you ... regular cocaine users do not look like this,” said Lawson, who boasts a voluptuous figure. She alleged her ex-husband had spread rumors about her supposed drug habit to discredit her.  Elisabetta and her sister, Francesca, 35, are accused of defrauding hotshot art dealer Charles Saatchi, 70, of over $1 million using his company credit cards.

Elisabetta testified that Lawson had smoked pot in front her children, smoked when she couldn’t fall asleep and stashed her cocaine in a hollowed out book. Lawson’s bedside table was filled with prescription drugs such as anti-depressants and sleeping pills, Elisabetta said, The Mirror reported.  Still, personal assistant said the drugs never came up in conversation.

Saatchi was labeled a wife beater following a stunning photo that showed him appearing to choke his wife at a London restaurant as their marriage fell apart. He would later say in court he was trying to make her pay attention.

One minute, Lawson would text Elisabetta, saying she loved her, and the next she would order her to return home from lunch to pick parsley off the floor, Elisabetta testified, according to The Mirror, adding that Saatchi also was “shouty” and “not very nice.”  But the Italian-born Grillo sisters’ high-flying lifestyle was not a secret, Elisabetta said.  “I still think I did nothing bad. I still think it was allowed and I was allowed - Nigella told me,” Elisabetta testified.  On Wednesday, it was revealed in court that Lawson had signed an exclusive deal for an interview with Oprah Winfrey — likely in preparation for an attempt to resurrect her flailing career.  ABC has said it is considering whether to invite her back for a third season as a judge on “The Taste” reality TV cooking show.
