Katie Price could face jail time after she was arrested on suspicion of breaching a restraining order.
Police were called to the former glamour model’s home in Sussex on Friday after unconfirmed reports claimed the 43-year-old sent a message to her ex-husband, Kieran Hayler, and his fiancee, Michelle Penticost.
A spokeswoman for Sussex Police said: "At 5:45 pm on Friday (21 January) police responded to a report that a suspect had breached their restraining order.
"Officers arrested a woman in her 40s who has been released under investigation while inquiries continue."
She was fined hundreds of pounds for a foul-mouthed "tirade of abuse" at her during a row in a school playground.
In December, Price was handed a 16-week suspended sentence and a two-year driving ban for drink-driving without insurance, while she was disqualified.
She was driving to visit a friend in Sussex when the crash happened at about 6:20 am on 28 September.
Her representative has been contacted for comment.
