Nigella Lawson has broke her after drug use accusations.

Nigella Lawson has hit back at sensational drug allegations made by her former husband, Charles Saatchi.

The TV chef broke her silence to thank fans for their support after Saatchi claimed in court that she was a drug addict who used cocaine, cannabis and prescription pills on a daily basis during their 10-year marriage.

In the defiant tweet, she shared a Holiday Hotcake recipe with her 473,000 followers and urged them to use the hashtag #teamNigella.

She tweeted: "Holiday Hotcake: the perfect recipe to show thanks for all your support & to those who hashtag #teamNigella."

Within minutes her timeline was bombarded with messages of support from fans and the post was retweeted hundreds of times.

"That's the spirit," one person wrote.

Saatchi claimed in an email read out in court that Lawson fought hard to conceal her "guilty secret" because she knew he would "not have condoned" her behaviour.

The multimillionaire's allegations emerged ahead of a fraud trial of two sisters who used to work as personal assistants to the celebrity couple.

Italian sisters Francesca Grillo, 34, and Elisabetta Grillo, 41, are accused of racking up a £300,000 bill on Saatchi's company credit card after making extravagant purchases such as holidays and designer handbags.

The defendants deny the charges.

Saatchi claimed that the Nigella Bites star was "so off her head on drugs" that she allowed the assistants to get away with murder.

Lawson's lawyers slammed the claims as "totally scurrilous" and untrue.
