Two months after revealing Shia LaBeouf "conned" her "into an adulterous relationship claiming to be single," Sia revealed more details about her romance with the actor during an interview with\u00a0The Sunday Times, saying that she and FKA Twigs both thought they were "singly dating him" when "he was still married." \u201cIt 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,\u201d Sia explained. \u201cBoth of us thought we were singly dating him. But that wasn\u2019t the case. And he was still married.\u201d The singer-songwriter went on to say that LaBeouf\u00a0\u201cwanted to marry me and live a sober life\u201d together, and despite the toxicity she'll always have a place in her heart for him. \u201cI feel like I\u2019m always gonna love him because he\u2019s such a sick puppy," she admitted. Sia decided to tell her story after Twigs (real name Tahliah Barnett) went public with a lawsuit accusing LaBeouf of sexual battery, assault, emotional distress and \u201cknowingly\u201d transmitting a sexually transmitted disease during their relationship, which spanned nearly a year between 2018 and 2019. Earlier this week, LaBeouf's legal team said in a statement that the actor \u201cdenies, generally and specifically, each and every allegation contained in \u2019s Complaint, denies that has sustained any injury or loss by reason of any act or omission on the part of , and denies that is entitled to any relief or damages whatsoever.\u201d And that's not all, LaBeouf is also asking she pay his\u00a0legal fees and "further relief as the Court may deem just and proper."
