FKA twigs is revealing more about her former relationship with actor Shia LaBeouf during which she alleges he abused her.

In December, the British singer-songwriter, whose real name is Tahliah Debrett Barnett, filed a lawsuit against LaBeouf accusing him of sexual battery, assault, and causing emotional distress.

In February, the 33-year-old sat down with "CBS This Morning" co-anchor Gayle King and spoke in-depth about the alleged trauma she went through.

"He would often just start having an argument with me in the middle of the night, start accusing me of doing all sorts of things, planning to leave him in my head," Barnett said. "He'd wake me up, tell me I was disgusting, that I was vile."

"But this is the thing — but I would really doubt myself. You know, especially when I'd, like, wake up and he'd be like, 'You were lying there with your eyes open, planning to leave me.' And I'd be like, 'I literally was asleep,'" she added.

Barnett emphasized that nothing LaBeouf ever accused her of was true. She also claimed that he would "only want me to sleep naked because he said if I didn't then I was keeping myself from him."

A rep for LaBeouf did not immediately return Fox News' request for comment.

The musical artist insisted it wasn't "one set moment" that made her reevaluate their relationship but rather "subtle" things. The couple dated for nine months back in 2018. 

"That's the thing about, you know, domestic abuse, domestic violence, that it's a real gradual step-by-step process to get somebody to a place where they lose themselves so much that they accept or feel like they deserve to be treated in that way," she reasoned.

In Elle magazine's March 2021 issue, Barnett said recovering from her allegedly abusive relationship has been the "hardest" part.

"The biggest misconception is, ‘Well, you’re smart. If it was that bad, why didn’t you leave?’ " she explained to the outlet. "It can happen to anyone... It made me realize I need to come forward and talk about my experience. What I went through with my abuser is, hands down, the worst thing (I’ve experienced) in the whole of my life."

Now, though, Barnett is feeling more empowered than ever and is working on many new creative projects. 

"I have my life back. I can work as late as I want. I can see my friends," she said. "To be able to hit up Dua Lipa on Instagram, make a song with her, perform on her livestream, and have a new friend… and there’s no anxiety behind it. No fear of, like, ‘What is this going to cause for me? What trouble am I going to be in?’"

In December, LaBeouf, 34, told The New York Times, he was "not in any position to tell anyone how my behavior made them feel."

"I have no excuses for my alcoholism or aggression, only rationalizations," his statement continued. "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."

After the suit was filed, LaBeouf's lawyers said the entertainer "denies, generally and specifically, each and every allegation."

In another statement to CBS, LaBeouf's lawyer said, "A lawyer issuing general denials to all the allegations in a lawsuit is standard procedure in civil practice and signals nothing about Shia’s past statements or his acceptance of responsibility for things he has done wrong. Nothing has changed."

"Shia needs help and he knows that," LaBeouf’s attorney said to Variety at the time. "We are actively seeking the kind of meaningful, intensive, long-term inpatient treatment that he desperately needs."
