Nigella Lawson and husband's assistants allegedly bilked them out a million

Nigella Lawson's ex-husband Charles Saatchi is defending drug claims made against his wife.

Two assistants, sisters, are acused of defrauding the rich couple.

Saatchi, the millionaire ex-husband of celebrity chef Nigella Lawson, said Friday he believed his ex-wife had taken drugs but had no evidence of it.

The former assistants, Italian sisters Francesca and Elisabetta Grillo, are accused of stealing hundreds of thousands of pounds on company credit cards.

Allegations of drug use by Lawson were made in a pre-trial hearing for the case earlier this week, when an e-mail sent by Saatchi to Lawson in October was read out by the defense.

CNN reports that in an email, Saatchi wrote that the assistants would likely "get off" because Lawson was using cocaine and marijuana on a daily basis and "allowed the sisters to spend whatever they liked."

However Saatchi said he was "bereft" that the email had been made public.

He claims he never saw his wife taking drugs during their 10-year marriage and that he had no hard evidence she had done so.

Saatchi was shown a list of the top 50 transactions made by the two sibling assistants totaling more than $1 million, which he had not authorized.

Lawson is a judge on the ABC reality show "The Taste" in the United States. A second season will air in January.
