Katie Price has admitted shouting a “tirade of abuse” at her ex-husband’s new partner in a school playground.
The former model was due to stand trial over the incident which happened in Shipley, West Sussex, on 6 September.
She had originally denied using threatening, abusive, words or behaviour to cause harassment, alarm or distress to Kieran Hayler’s girlfriend.
But Price, 41, of near Horsham, changed her plea at the town’s magistrates’ court earlier.
The row with Michelle Penticost – who is dating Mr Hayler – and Ms Penticost’s friend Andrea Quigley happened in the playground of a primary school near Price’s home.
Paul Edwards, prosecuting, told the court that during the row, Price was witnessed hurling a “tirade of abuse” and swore multiple times at both women.
Paul Macauley, defending, claimed the outburst was prompted by Price’s recent discovery of Ms Penticost’s relationship with Mr Hayler.
Magistrates have retired to deliberate her sentence.
Earlier this year, Price revealed she had been “self-medicating” with cocaine for about six months, after what she said had been an “awful year” in 2018.
In an interview with the Victoria Derbyshire programme, she spoke about her mother’s terminal illness, splitting from her husband and being held at gunpoint in South Africa.
