Nigella Lawson has admitted to using cocaine and cannabis in a London court today in the fraud case against her two former personal assistants, but denies being a habitual drug user.

The domestic goddess, 53, testified that she had used cocaine “a handful of times”, revealing that she had used it when her late husband John Diamond was terminally ill with cancer.

She also confirmed she used it in 2010 while she was “subjected to intimate terrorism” by her now ex-husband Charles Saatchi.

The TV chef also admitted to smoking cannabis, including times in front of her children.

“The idea that I’m a drug addict or a habitual user of cocaine is absolutely ridiculous,” she said in court. “People who do that are a lot thinner than I am.”

The revelation came just a week after Saatchi claimed Lawson used cocaine, class B drugs and prescription drugs for more than a decade, which their former assistants used against the couple in order to defraud them of over $532,000 worth of designer goods, luxury hotels and first-class flights.

Lawson added: “I have to say, since freeing myself from a brilliant but brutal man, I’m now totally cannabis-, cocaine-, any drug-free.”

She also discussed the throat-grabbing incident in June which prompted their divorce. Lawson claims that she commented on how much she looked forward to having grandchildren, and in response, Saatchi grabbed her and said “I am the only person you should be concerned with. I am the only person that should give you pleasure.”

The trial continues on Thursday.
