the latest twist in the court case of celebrity chef nigella lawson. Tales of her alleged drug use are hitting the headlines. This as her assistants go on trial, accused of stealing hundreds of thousands of dollars from her and her ex-husband. He is also taking the stand and speaking about that shocking photo. This went global, where he was grabbing her neck at dinner. Monica has more from our london bureau. Good morning, monica. Reporter: Good morning, bianna. The famous art collector, charles saatchi, testified against his former employees, the grillo sisters, who allegedly spent thousands of dollars using his credit card. He said he offered them to work to pay back some of the money. But they did not settle for the deal. Another day, another twist in the celebrity trial that has gripped the u.K. Millionaire charles saatchi is now trying to clear his ex-wife's name in court. A sort of damage control. Testifying in the trial against nigella's personal assistants, he said, I have never, ever seen any evidence of nigella taking any drugs whatsoever. The art collector claimed the opposite in an e-mail to nigella. Calling her high-gella. Saying she was so off her head in drugs, she didn't notice her assistants spending $1 million on themselves. Outraged that the e-mail was read out in court, he said, it was an angry reaction. And a warning that the grillo sisters ths would use her alleged drug use. I think the heart of this case really goes back to a dispute between an employee and employer. It's so easy. And yet, so perfect. Reporter: Known as the domestic goddess, the chef's marriage collapsed after these pictures were published last june. In his first public appearance since the photos, saatchi says he's brokenhearted and added, i was not gripping or throttling her. I was holding her by the neck to make her focus. Abc news reached out to nigella, who won't make any comments while the trial is ongoing. And the trial so far has mostly focused on the celebrity couple. And not so much on the defendants charged with fraud. Many here are eager to hear what nigella has to say when she takes the stand next wednesday. And nigella lawson will be hosting the tv show, "the taste," which is on abc next january.
