Sia has provided new details on her romance with Shia LaBeouf, revealing they dated at the same time he was in an allegedly abusive relationship with FKA Twigs.
Sia has opened up about her past relationship with actor Shia LaBeouf amid allegations of abuse against the star.
LaBeouf appeared in the 2015 music video for Sia's track, Elastic Heart, alongside dancer Maddie Ziegler.
The Aussie singer, 45, revealed she had been in an "adulterous relationship" with LaBeouf while he was still with FKA Twigs, who has alleged he assaulted her during their one-year relationship.
Speaking to The Sunday Times over the weekend, Sia said she was "always gonna love" LaBeouf, after revealing she had been "hurt emotionally" by the actor.
"It turns out he was using the same lines on me and Twigsy, and eventually we found out because we ended up talking to one another," Sia told the outlet.
"Both of us thought we were singly dating him. But that wasn't the case. And he was still married."
LaBeouf married actress Mia Goth in 2016, but filed for divorce two years later. He struck up a romance with FKA Twigs in 2019 on the set of the film Honey Boy.
Twigs, 32, whose real name is Tahliah Debrett Barnett, took legal action against him in December, alleging that the Hollywood star was a danger to women.
She said LaBeouf once tried to strangle her, slammed her into a car and became angry when she spoke to other men. She is suing him for physical, mental and emotional abuse, claiming that their relationship turned into a "living nightmare".
Last week, 34-year-old LaBeouf denied "each and every" assault allegation by Twigs.
The response stated that LaBeouf "denies, generally and specifically, each and every allegation contained in [Barnett]'s Complaint, denies that [Barnett] has sustained any injury or loss by reason of any act or omission on the part of [LaBeouf], and denies that [Barnett] is entitled to any relief or damages whatsoever".
When Twigs' lawsuit against LaBeouf was first made public, Sia tweeted her support, revealing her own experiences with the star.
"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 went on to reveal she had sacked him from a starring role in her controversial film Music.
"I was going to do a narrative film, and in fact, Shia LaBeouf was cast to play Kate (Hudson's) character," Sia told Studio 10.
"I asked for a meeting with her, and she said she was born to do it. She could sing, she could dance, she could do it all."
Over the weekend, Sia told The Sunday Times that LaBeouf "wanted to marry me and live a sober life."
She added: "I feel like I'm always gonna love him because he's such a sick puppy."
Sia was married to documentary filmmaker Erik Anders Lang from August 2014, until December 2016, when the couple announced their separation.
It was not known that Sia and LaBeouf had ever dated, or when exactly they were in a relationship.
