Actress Kristen Stewart attended the premiere of \"On the Road\" at the Toronto Film Festival, making her first public appearance since her July cheating scandal. Stewart, 22, wore a black Zuhair Murad dress to the Thursday premiere of her latest film, co-starring Garrett Hedlund, the New York Daily News reported Friday. She spent more time interacting with fans and signing autographs than answering questions from reporters, the News said. The \"Twilight\" star had been in seclusion since July when photographs surfaced of her making out with her married \"Snow White and the Huntsman\" director, Rupert Sanders. The incident ended her three-year relationship with \"Twilight\" co-star, Robert Pattinson. When asked how she was holding up, Stewart told Canada\'s CTV News she was \"doing fine.\"
