TV star Katie Price has denied being abusive outside a school.
The 40-year-old reality star is charged with one count of using threatening and abusive words or behaviour outside a primary school in Shipley last September.
Crawley Magistrates' Court heard she was involved in a "verbal altercation" with Michelle Pentecost, the girlfriend of her ex-husband Kieran Hayler.
When read the charge, Ms Price replied: "Definitely not guilty."
The former model, of Dial Post, near Horsham, West Sussex, is due to stand trial at Horsham Magistrates' Court on 3 June.
A second charge of using threatening or abusive words or behaviour was dropped.
Prosecutor Georgina Kent told the court Ms Price had used foul language towards Ms Pentecost and another woman next to the school playground on 6 September.
The court heard the argument had been witnessed by two teachers.
Ms Price, who stood in the dock holding her mobile phone, had been due to appear before magistrates in Crawley on 13 March but failed to turn up.
When reminded by chairman of the bench Serena Stewart of the importance of attending the trial in June, Ms Price replied: "I will definitely be attending, don't worry about that."
