When Kristen Stewart and Robert Pattinson first got together, it seemed like a match made in "Twilight" heaven. But it looks like the famous couple won't get their happily ever after. Ironically, it was Stewart's role in a fairy tale adaptation, "Snow White and the Huntsman," that brought her together with a new romantic interest: the film's director, Rupert Sanders. They got really close on July 17, 2012, when they were photographed in a series of steamy make-out sessions in a car in Los Angeles. Afterward, Stewart ditched her notoriously private ways and issued a public apology for her indiscretions. "I'm deeply sorry for the hurt and embarrassment I've caused to those close to me and everyone this has affected. This momentary indiscretion has jeopardized the most important thing in my life, the person I love and respect the most, Rob. I love him, I love him, I'm so sorry," she said in a statement.
