Sia has come forward with her own accusations against Shia LaBeouf on the heels of FKA twigs filing a lawsuit, in which she accuses the actor of "relentless abuse" during their relationship.

"I too have been hurt emotionally by Shia, a pathological liar, who conned me into an adulterous relationship claiming to be single," Sia alleged in response to FKA twigs claims on Saturday. "I believe he's very sick and have compassion for him AND his victims. Just know, if you love yourself- stay safe, stay away."

She added in a second post, "Also I love you @FKAtwigs. This is very courageous and I'm very proud of you."

Sia and LaBeouf collaborated on the music video for her 2015 hit "Elastic Heart." Details about their relationship are currently unclear. EW has reached out to representatives for Sia and LaBeouf for comment.

FKA twigs (born Tahliah Debrett Barnett), who dated LaBeouf in 2018 for just shy of a year, accused her former boyfriend of inflicting physical, emotional, and mental abuse on Friday.

In response to the story, the Transformers star emailed the New York Times, which initially broke FKA twig's account, about his relationship with the singer and Karolyn Pho, a former stylist whose alleged allegations against LaBeouf of physical and mental abuse are also recounted in the lawsuit.

"I'm not in any position to tell anyone how my behavior made them feel," he told the outlet on Thursday. "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."

In a follow-up email about the lawsuit, he said "many of these allegations are not true" but he felt he owed the women "the opportunity to air their statements publicly and accept accountability for those things I have done." He said while he's "a sober member of a 12-step program," he's not been cured of his "PTSD and alcoholism." Adding his commitment to "doing what I need to do to recover" and that he'll "forever be sorry to the people that I may have harmed along the way."
