Liberty Ross, Mr. Sanders‘ wife of more than nine years, filed for divorce Friday in Los Angeles.
Miss Ross‘ filing cites irreconcilable differences for the couple’s breakup. They have two children, an 8-year-old daughter and 6-year-old son.
The model-actress is seeking joint custody of the children and spousal support from her estranged husband, who directed Miss Stewart in “Snow White and the Huntsman.”
TMZ, which first reported the filing, said Mr. Sanders also filed divorce paperwork but it was not available on Monday.
Miss Stewart, who has been dating “Twilight” co-star Robert Pattinson, apologized for her fling with Mr. Sanders in July after it was revealed by US Weekly.
