Kristen Stewart's rival Liberty Ross hits the runway

NEW YORK (AP) - While Kristen Stewart promoted a new film in Toronto, her romantic rival took to the runway.

Liberty Ross, the wife of Snow White And The Huntsman director Rupert Sanders, walked the catwalk during the Alexander Wang show on Saturday at New York Fashion Week wearing a white wind-breaker with a pencil skirt.

Ross, 33, has mostly retired from modeling and recently appeared in Snow White And The Huntsman as Stewart's mother.

Stewart and Sanders issued public apologies following tabloid reports they had a brief affair while Stewart was dating her Twilight co-star Robert Pattinson.
