Sia has accused Shia LaBeouf of double dating herself and FKA twigs. The Chandelier singer previously called out the troubled actor for allegedly conning her "into an adulterous relationship claiming to be single" after twigs, real name Tahliah Debrett Barnett, filed a lawsuit against Shia for abuse and sexual battery in December, and now the Australian star has confirmed she was unaware she was part of a bizarre love triangle with the former couple.
