Sia has filed for divorce from second husband Daniel Bernard after two years of marriage.
The Grammy-nominated Australian singer-songwriter, whose legal name is Sia Furler, filed the petition in Los Angeles Superior Court.
It listed Tuesday as their separation date.
As happens in the vast majority of California divorces, she cited irreconcilable differences as the reason.
The singer asked the court to award no spousal support payments to Bernard.
She is also seeking legal and physical custody of their 11-month-old child, Somersault Wonder Bernard.
It is not clear when the secretive singer began dating Bernard, or how they met.
They were legally married in December 2022 and had a small marriage ceremony in Portofino, Italy, the following May.
From 2014 to 2017, Sia was married to filmmaker Erik Anders Lang.
The 49-year-old singer has been nominated for nine Grammys.
Five of them were for her 2014 hit Chandelier.
