Last month, LaBeouf denied claims made by his ex-girlfriend, singer FKA Twigs, who filed a lawsuit claiming he "relentlessly" abused her emotionally, physically and mentally.
Fellow singer Sia also called the actor a "pathological liar" on Twitter, and confirmed she had replaced him in her upcoming film Music.
"I too have been hurt emotionally by Shia, a pathological liar, who conned me into an adulterous relationship claiming to be single. I believe he's very sick and have compassion for him AND his victims," she wrote.
One incident described in Twigs' lawsuit against LaBeouf occurred just after Valentine's Day 2019. Twigs claims LaBeouf was driving recklessly, threatening to crash the car if Twigs, a passenger, didn't profess her love for him.
She claims she begged to be let out of the car and LaBeouf pulled over at a gas station, followed her out of the car and assaulted her, throwing her against the car, according to the lawsuit.
The two were driving home from a trip to the desert during which the Honey Boy star allegedly raged out and woke Twigs up one night and choked her.
"I'd like to be able to raise awareness on the tactics that abusers use to control you and take away your agency," Twigs told The New York Times.
Twigs and LaBeouf first met in 2018 when she joined the cast of Honey Boy, but didn't start dating until after filming wrapped.
In the lawsuit, Twigs, born Tahliah Debrett Barnett, claims LaBeouf knowingly gave her a sexually transmitted disease. She also claims he would grab her so hard, she would bruise.
She says she didn't go to police at first out of fear of harming her career and not being taken seriously.
LaBeouf said in an email to The New York Times: "I'm not in any position to tell anyone how my behaviour made them feel. I have no excuses for my alcoholism or aggression, only rationalisations."
"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."
