The film producer wife of Clash singer Mick Jones slapped a French jewellery designer across the face and trashed an antique jewellery display in blazing row over money, a court heard.
Miranda Gian Davis, 53, is accused of attacking designer Jan Cremer and wrecking two necklaces worth more than 6000 euros during the outburst.
She had rented her apartment in Holland Park, west London, out to Ms Cremer and fellow French designer Michele Jarry Des Loges.
But during a row over unpaid money, Davis alleged slapped Ms Cremer and "destroyed" the jewellery belonging to Ms Des Loges.
Davis, who has two children with Clash lead singer Mick Jones, made her name as a film producer with the 2003 hit Bright Young Things, starring Emily Mortimer and James McAvoy.
The film, directed by her friend Stephen Fry and based on an Evelyn Waugh novel, chronicles the drug and alcohol fuelled parties of a group of socialites in the 1930s.
Davis, wearing all black with a floral scarf, appeared at Hammersmith Magistrates Court this morning to plead not guilty to charges of criminal damage and common assault.
Prosecutor Sadaf Etemadi said: "The two complainants are involved in antique jewellery making, and on the day in question there was jewellery on display.
"An argument has taken place between the complainant and the defendant.
"The complainants allege the defendant was stating they owed her money.
"The defendant has slapped Ms Cremer and damaged the jewellery."
Ms Etemadi said the necklaces were worth more than 6000 euros and Davis had "thrown the jewellery from where they were placed."
The outburst allegedly took place on December 11 last year and was caught on camera by one of the victims, the court heard.
However, Samuel Langi, defending, said Davis denies slapping Ms Cremer and disputes that the necklaces were damaged at all.
The victims have now moved out of her flat and returned to Paris, the court heard.
District Judge Andrew Jones freed Davis on unconditional bail until her trial, which is due to take place on June 22.
