Singer FKA Twigs has accused her ex, actor Shia LaBeouf, of "relentless abuse" in a new lawsuit.
Twigs - real name Tahliah Barnett - says the Transformers star knowingly gave her an STD, suing him over claims of sexual battery, assault, and infliction of emotional distress, US media reported.
"We tried to resolve this matter privately on the condition that Mr LaBeouf agree to receive meaningful and consistent psychological treatment," her lawyer Bryan Freedman told The Hollywood Reporter.
"Since he was unwilling to agree to get appropriate help, Ms Barnett filed this suit to prevent others from unknowingly suffering similar abuse by him."
The pair met in 2018 on the set of film Honey Boy. They split in May.
The New York Times reported some of the disturbing details in the documents filed by Barnett. In February, LaBeouf allegedly drove dangerously, without a seatbelt on, threatening to crash the vehicle they were travelling in unless the 'Ego Death' singer professed love for him.
In another incident she says she woke up in the middle of the night to find LaBeouf choking her, and another involved him allegedly assaulting her at a gas station.
A second former girlfriend of the Indiana Jones star told the Times he once headbutted her so hard she bled.
LaBeouf said while "many of these allegations are not true", he said he had to "accept accountability for those things I have done", saying he was seeking help.
"I'm not in any position to tell anyone how my behaviour made them feel," he wrote in an email to the Times.
"I have no excuses for my alcoholism or aggression, only rationalizations. I have been abusive to myself and everyone around me for years. I have a history of hurting the people closest to me. I'm ashamed of that history and am sorry to those I hurt. There is nothing else I can really say."
LaBeouf has had a number of run-ins with the law, and has previously sought treatment for alcoholism.
