Nigella Lawson has arrived at court for a second day to finish giving evidence in the trial of two of her former personal assistants.
As she got out of her vehicle at Isleworth Crown Court in west London, she was met by photographers, broadcasters and reporters.
Yesterday the TV cook admitted using cocaine and spoke of the "intimate terrorism" she suffered at the hands of former husband Charles Saatchi.
Italian sisters Francesca Grillo, 35, and Elisabetta, sometimes referred to as Lisa, 41, are accused of committing fraud by abusing their positions by using a company credit card for personal gain.
Jurors were previously read an email sent to Ms Lawson from Mr Saatchi in which he said the Grillo sisters would "get off" on the basis that she was so off her head on drugs that she allowed them to "spend whatever they liked".
She said she took cocaine with her late husband John Diamond when he found out he had terminal cancer, and on another occasion during her troubled marriage to Mr Saatchi.
But the 53-year-old, who also admitted smoking cannabis, said the idea that she is a "drug addict or habitual user of cocaine is absolutely ridiculous".
Standing in the witness box, Ms Lawson admitted taking cocaine on six occasions with her late husband Mr Diamond.
"It gave him some escape," she told the court.
"There was another time I took cocaine.
"In July 2010 I was having a very, very difficult time.
"I felt subjected to intimate terrorism by Mr Saatchi."
Ms Lawson said she felt "isolated and in fear of... just unhappy".
"A friend of mine offered me some cocaine. I took it," she said.
Ms Lawson told the court the experience "completely spooked" her.
The Grillo sisters, of Kensington Gardens Square, Bayswater, west London, deny the charge against them.
The pair are accused of using credit cards loaned to them by the TV cook and her ex-husband to spend more than £685,000 on themselves between 2008 and 2012.
Prosecutors claim the Grillos lived the ''high life'', spending the money on designer clothes and handbags from Louis Vuitton, Christian Dior and Vivienne Westwood.
