Kristen's mother, Jules Stewart, filed a divorce petition against John Stewart, who she married 27 years ago. She filed the papers at County Superior Court, here citing irreconcilable differences, reports tmz.com.
Jules filed the documents herself without using a lawyer one month after her daughter was photographed embracing her "Snow White and the Huntsman" director Rupert Sanders, despite dating her 'Twilight' co-star Robert Pattinson.
Kristen's mother, who is a writer-director and has worked for Fox, says she has been estranged from John, a TV producer and stage manager, since June 15, 2010.
