Cheating can never result in something good. Cheating on exams, in contests, and most especially cheating with a married man.

Sadly, Kristen Stewart is learning this the hard way: after her scandalous affair with director Rupert Sanders, not only has long-time boyfriend Robert Pattinson broken up with her, but she is reportedly puling out from her role in the upcoming romantic drama, "Cali."

The 22-year old actress was billed to play opposite "Magic Mike" star Alex Pettyfer, with the movie to be helmed by Nick Cassavetes, known for directing the 2004 romantic drama, "The Notebook."

After her drop out, rumors have immediately circulatd as to who will replace the "Twilight" star.

"As of Thursday, some of Hollywood's biggest names have been mentioned as possible replacements for Stewart, including Amber Heart (The Rum Diary) and Oscar-nominated beauty Carey Mulligan (An Education; The Great Gatsby). The film, about a couple who comes out of hiding to save the girlfriend's sister, is supposed to hit theaters next year." reports Celebuzz.

Stewart has been reported to focus on getting back with Robert Pattinson, which apparently for Kristen, is a good enough reason to drop her upcoming projects.

However, the Kristen-Robert breakup is not the only reason as to why "Twilight" fans, or Twi-hards, might break their hearts: news have been revealed that the ending of the "Twilight" saga has been changed.

"'When I first read the script, I got to that part and was like, "What?"' Robert Pattinson tells Entertainment Weekly. 'And then I had to go back a page.'" reports Hollywood Life regarding the lead actor's reaction to the radical change.

Kristen also reacted, saying that the new script was made by someone who loved the films.

"'It's clearly made by someone who really likes [the saga], who really cares,' she says. 'That's why [director] Bill Condon is perfect. Thank God for him.'" continued Hollywood Life.

However the fans might react, the change was done in good taste, as it was discussed over dinner by the author Stephanie Meyer and screenwriter, Melissa Rosenberg.

Sure enough, despite thisreported change, fans will still be lining up in theatres when the finale hits cinemas mid-November.
