The estranged wife of celebrity chef Marco Pierre White has been cleared of assault after son Marco Jr was "too hungover" to give evidence against her.
Matilde White, who is separated from their father and known by her maiden name Conejero, was accused of attacking her adult sons, Luciano and Marco Jr.
She allegedly "burst her way" into Marco Jr's Chiswick flat and told him: "You're a f***ing loser junkie - you're going to prison."
White apparently then kicked Marco Jr in the groin repeatedly before dragging him along by the hair.
When Luciano tried to separate them, she allegedly lashed out at him and bit him on the arm.
The trial collapsed after both Luciano and Marco Jr failed to attend Uxbridge Magistrates' Court on Tuesday, where they were due to give evidence.
Marco Jr, who recently appeared on Big Brother, told police he was "too hungover" to attend after apparently going out partying last night. Police were unable to make contact with Luciano.
District Judge Deborah Wright dismissed the case after prosecutor Katie Weiss offered no evidence.
Michael Smith, defending, said Marco Jr's attitude to the criminal justice system was "utterly outrageous".
White, 51, of Chiswick High Road, London, was formally cleared of two counts of common assault by beating.
She denied the charges and claimed she was acting in self defence during the incident on September 20 last year.
