Alex Pettyfer and Dianna Agron split just a PR move (to promote Tyler Shields)?

Dianna Agron (who plays Quinn on Glee) started dating her I Am Number Four costar Alex Pettyfer about a year ago, and because they never officially confirmed that they’re dating many believed that their relationship was just a marketing ploy for the film.

The publicity coming from their recent split has also raised red flags of craziness. First, the story was that Dianna broke up with him over a racy Tyler Shields photo-shoot Alex did a few months before they started dating with models Lydia Hearst and Leven Ramblin.

Now there are stories making the rounds that Alex was crazy and controlling, and that Dianna is now “terrified” of him. Is any of this true, or are the PR spinmasters just trying to get some buzz for the film, and for photographer Tyler Shields?

Word of this latest Hollywood breakup hit the papers after rumors of an engagement. I Am Number Four debuted #2 at the box office this weekend, just getting beat out by Unknown.
