Sia’s estranged husband, Dan Bernad, has accused the singer of being “unfit” to care for their one-year-old son, Somersault Wonder Bernad, as their divorce battle intensifies.
In legal documents filed this week, Bernad — an oncologist — alleged that Sia poses a “serious and immediate danger” to their child, citing her past struggles with sobriety as evidence that she cannot provide a stable home.
“Sia is an unfit and unreliable parent struggling with substance abuse and addiction, rendering her incapable of providing safe or stable care for Summi,” Bernad stated in his request for sole custody. “I am the only safe and reliable parent for our son. I am a doctor, young, healthy and have no criminal history or drug or alcohol addiction issues.”
He further claimed that Sia had never been the primary caregiver for Somersault, alleging that she “delegated nearly all child-rearing responsibilities to a revolving team of nannies while she maintained control from a distance.”
In her response, the 49-year-old Chandelier singer pushed back against the accusations, accusing her estranged husband of “weaponizing” her history of substance abuse.
“I have been fully sober for over six months and working my program which includes weekly testing and a sober companion,” she stated in her filing. “My recovery has been a cornerstone of my life and one of the primary reasons I chose to separate from Dan, whose ongoing engagement in a nightlife and recreational drug-use lifestyle is incompatible with a healthy environment for our child.”
Sia filed for divorce from Bernad in March after two years of marriage. The couple’s custody dispute adds a new layer of complexity to their separation, with both parties now fighting to prove who can best provide a stable environment for their young son.
