Rupert Sanders' wife seeks divorce

Director Rupert Sanders' wife has filed for divorce five months after it was revealed that he had a brief affair with actress Kristen Stewart.

Liberty Ross, Sanders' wife of more than nine years, filed for divorce in Los Angeles, citing irreconcilable differences.

The couple have two children, an eight-year-old daughter and six-year-old son.

The model-actress is seeking joint custody of the children and spousal support from her estranged husband, who directed Stewart in Snow White And The Huntsman.

Stewart, who has been dating Twilight co-star Robert Pattinson, apologised for her fling with Sanders in July after it was revealed by US Weekly.
