Kristen's mother Jules filed a divorce petition against John Stewart, her husband of 27 years. She filed the papers at County Superior Court here citing irreconcilable differences, reported TMZ Online.
The divorce news comes one month after Kristen was photographed embracing her "Snow White and the Huntsman" director Rupert Sanders, despite dating her "Twilight" co-star Pattinson.
Jules filed the documents herself without using a lawyer and she stated she has been estranged from John, a TV producer and stage manager, since June 15, 2010.
