The fairy tale is over! Evil grumpus Kristen Stewart has cheated on her sparkle-hunk bf, and shit’s about to hit the fan, making for some VERY AWKWARD red carpet strolls come November. (*Rubs hands together with glee.*) The man who came between them? MARRIED Snow White and the Huntsman director Rupert Sanders, 19 YEARS HER SENIOR! Says HuffPo: “Photos of the tryst, which supposedly took place on July 17, appear in this week’s Us Weekly. People Magazine‘s latest issue covers the same story with the addition of a quote from a source who says ‘Kristen is absolutely devastated’ and that it was ‘a mistake and a complete lapse in judgment’ and a ‘fleeting moment,’ not an affair.” Of course the couple seemed absolutely fine when they appeared onstage at the Teen Choice Awards Sunday, whispering and laughing and whatnot, so who the hell knows.
