Katie Price faces jail time after being arrested on suspicion of violating a restraining order.
Police were called to the Sussex home of the former glamor model, known professionally as Jordan, on Friday.
The sun reported that Price, 43, had sent an abusive message to her ex-husband Kieran Hayler and his fiancee Michelle Penticost.
A spokeswoman for Sussex Police said: “At 5.45pm on Friday (21 January) police were responding to a report that a suspect had breached his restraining order.
“Officials have arrested a woman in her 40s who has been released as part of an investigation while the investigation continues.”
Price was banned from contacting Penticost in 2019 under the terms of a five-year injunction.
She has been fined hundreds of pounds for hurling a foul “abuse rant” at her during an argument in a schoolyard.
December was Price sentenced to a 16-week suspended sentence for drunk driving while she was disqualified and uninsured, as well as a two-year driving ban.
She was driving to a nearby friend in Sussex when the accident happened around 6.20am on September 28.
