The fans have released a video on YouTube, which claims to show how public relations executives staged the 22-year-old actress' affair with married director Sanders, News.com.au reported.
Theories about the affair have intensified in the past few days after it became apparent that Robert Pattinson was going to take Stewart back in his life.
Chatrooms, blogs and fan sites have been filled with theories that the intimate photographs of Stewart and Sanders published in Us Weekly in July were doctored.
According to the Huffington Post, 'For an actress who managed to keep her four-year relationship with Robert Pattinson relatively private, it seemed suspect that she could be so careless as to have her 'momentary indiscretion' in such a public place that's known to be swarmed with paparazzi.
'With the exception of drug benders and mental breakdowns, there are few things in Hollywood that aren't controlled by publicists, so it's no surprise that there are conspiracy theorists who believe the photos are fake and the entire cheating scandal was a publicity stunt,' the publication wrote.
Gossip and lifestyle website Crushable has been floating the publicity stunt idea for more than a month, the report said. 'From the very beginning, I suspected that the entire scandal reeked of a publicity stunt developed in a Hollywood marketing brainstorming meeting to boost the careers of everyone involved, from Kristen Stewart to Robert Pattinson to Rupert Sanders, and yes, even to Liberty Ross,' Crushable writer Jenni Maier wrote.
'And in the weeks since the scandal ripped open the hearts of every American, we've seen all four of their careers receive a huge publicity bump. Not only do average people now know the names Rupert Sanders and Liberty Ross, but they've gotten offered scripts, jobs and everything a Hollywood family could want,' she wrote.
Maier has said that Pattinson's movie Cosmopolis -- released in the wake of the scandal -- grossed more at the box office than it should have and that Ross walked the ramp for the first time in many years.
