One of the reasons Robert Pattinson isn’t Christian Grey in the “Fifty Shades of Grey” movie could be because ex-girlfriend Kristen Stewart told him it would be “career suicide,” if celebrity blogger Perez Hilton is to be believed. Pattinson was one of the top contenders among some fans and reportedly inspired author E.L. James to write the erotic series after her ardor for “Twilight.”

"Kristen told him '50 Shades' would be a disaster for him. He's haunted by 'Twilight' and being too identified with that role. Taking '50 Shades' would mean a worse label for the rest of his career,” the source told Hilton.

“Kristen told him that creatively, he shouldn't do it, but if it's about fame and money, he should. She told him he had to make the choice between the two, but warned that it would stick with him,” the insider added.

Pattinson has been in various films since wrapping up the “Twilight” series, but it still best known for his Edward Cullen character in the vampire movies. “Fifty Shades of Grey” is a trilogy like “Twilight,” and chances are there will be subsequent movies assuming the first film does well when it’s released sometime in 2014.

The source continued: "He pushed it away after Kristen's advice, even though his manager was very much for it. His family didn't interfere, but he knew his mum wouldn't like it either."

Rumors as to who would play Christian Grey finally ended on Sept. 2 when Charlie Hunnam was announced to have won the role. But after much criticism from fans and apparent scheduling conflicts, the 33-year-old “Sons of Anarchy” star dropped out of the film. Not long after, Hunnam was replaced by “Once Upon A Time” hunk Jamie Dornan, who is set to star in the film opposite Dakota Johson.

The movie was originally supposed to open Aug. 1, 2014, but after producers had to scramble to find a new Christian Grey just days before filming was supposed to begin in early November, the production start date was pushed back to Dec. 2, and it seems unlikely the project will be able to make its original debut date.
