Two sisters who worked as personal assistants for Nigella Lawson and Charles Saatchi have been cleared of defrauding the couple.
The two sisters, Francesca Grillo, 35, and Elisabetta, 41, had denied spending £685,000 on credit cards belonging to the TV cook and her ex-husband.
They claimed Ms Lawson authorised them to spend the money as she wanted them to keep quiet about her cocaine use.
Scotland Yard said it would not investigate the drug-taking allegation.
Detectives, however, said they will review the decision if new evidence comes to light, a spokesperson added.
The trial, involving a high profile TV personality and her high profile ex-husband generated a lot of attention nationwide especially with the revelation that the much respected chef, Nigella Lawson was taking drugs.
During the trial, the Prime Minister, David Cameron, earned rebuke from the judged when the PM was quoted saying he was in “team Nigella” while the trial was still ongoing.
The judged warned the jurors to disregard the PM’s endorsement of the celebrity chef.
Solicitor Richard Cannon said the sisters were “naturally relieved” by the verdict, following a “long, hard fight played out in the gaze of the world’s media”.
The trial at Isleworth Crown Court heard the sisters used credit cards loaned to them by the couple to buy designer goods from Louis Vuitton, Christian Dior and Vivienne Westwood.
But the sisters insisted all of their purchases had been authorised.
The pair claimed Ms Lawson consented to their spending as they were “intimately connected to her private life and were aware of the drug use which she wanted to keep from her then-husband Charles Saatchi”.
Giving evidence, Ms Lawson admitted taking cocaine a handful of times with her late husband John Diamond and once during her marriage to Mr Saatchi.
She denied being an addict or having a drug problem. The television cook said she was “not proud” but would rather be “honest and ashamed” about what she had done.
Elisabetta, who was rushed to hospital on Thursday night after a panic attack, was with her sister in another room in the court as the verdicts were read out. She had collapsed again earlier as she arrived at the building.
After hearing the verdicts, Francesca declared in Italian “There is a God.”
Her barrister, Ms Arden, was seen in the court foyer, proclaiming to her client: “C’e un Dio.” She replied “c’e un Dio” and the pair embraced.
After the three-week trial, the jury of seven men and five women rejected the prosecution’s claims that the purchases on the cards had been unauthorised.
