Moving trucks descended on the once-happy home of “Twilight” stars Kristen Stewart and Robert Pattinson over the weekend — as rumors swirled that the actress’ infidelity was more than just a brief fling. Shutterbugs outside the $6 million LA love nest snapped photos of U-Haul vans driving off Saturday in the wake of Stewart’s stunning admission she had a fling with her “Snow White and the Huntsman” director, Rupert Sanders, 41. The filmmaker, married to model Liberty Ross, also admitted to the extramarital affair.
