Ms Trumble claims she was unfairly dismissed
An employment tribunal hearing launched against Heather Mills by her former nanny has been delayed.
Sara Trumble, 25, of West Sussex, is seeking compensation from Sir Paul McCartney's ex-wife, alleging unfair dismissal and sex discrimination.
The case has been adjourned while the judge considers whether evidence heard during Ms Mills' divorce can be used.
The tribunal was told such evidence was relevant because it showed Ms Mills had lied under oath at the High Court.
The former model of Robertsbridge, East Sussex, was at the hearing in Ashford, Kent.
Sitting at the back, Ms Mills uttered a long "no" as solicitor Nick Fairweather said the High Court judgment should be used as it demonstrated her credibility.

Mr Fairweather said: "She [Mills] was found by a High Court judge under the forensic scrutiny of the High Court to have lied."
Caroline Crampton-Thomas, representing Ms Mills, said using the judgment would "unfairly prejudice" her client.
Ms Trumble, of Westfield, claims the terms of her employment were altered after she took maternity leave.
The tribunal heard that Ms Mills, who has a seven-year-old daughter with Sir Paul, will dispute the job title of her former employee and argue that she was also hired to work as a housekeeper.
