Remember the rumors swirling about I Am Number Four costars Alex Pettyfer and Dianna Argon getting engaged and soon after I Am Number Four was released, Alex and Dianna was said to have called it quits? Well, I’m not even sure if Jennifer Aniston and Gerard Butler , Taylor Swift and Taylor Lautner or Taylor Lautner and Lily Collins were even dating during the production and release of their movie!
Maybe it’s just me or maybe there are a lot of costars, rumored to be “couples”, who are just together when their movie is up and coming and soon after the movie is in theaters, guess what- it’s time to call it quits.
So according to sources, Alex Pettyfer and Dianna Argon’s relationship likely ended because of a case of infidelity. Whether or not cheating really did occur or even if there was really a romantic relationship, the source says Alex Pettyfer was “very controlling and would always take Dianna’s phone and read her messages and seemed really paranoid Dianna would cheat”.
